electrical, mechanical, and thermal specification 4-27 intel? pxa270 processor pin listing and signal definitions 4.3 signal types table 4-2. pin use and mapping notes note description [1] gpio reset/deep sleep operation: after any reset is asserted or if the px a270 processor is in deep sleep mode, these pins are configured as gpio inputs by default. the input buffers for these pins are disabled to prevent current drain and must be enabled prior to use by clearing the read disable hold bit, pssr[rdh]. until rdh is cleared, each pin is pulled high (pu-1), pulled low (pd- 0), or floated (hi-z). [2] crystal oscillator pins: these pins connect the external crystals to the on- chip oscillators and are not affected by either reset or sleep. for more information, see the ?clocks and power? chapter in the intel? pxa27x processor family developer?s manual . [3] gpio sleep operation: during the transition into sleep mode, the confi guration of these pins is determined by the corresponding gpio setting. this pin is not driven during sleep if the direction of the pin is selected to be an input. if the direction of the pin is selected as an output, the value contained in the power manager gpio sleep-state register (pgsr0/1/2/3) is driven out onto the pin and held while the pxa270 processor is in sleep mode. upon exit from sleep mode, gpios that are configured as outputs continue to hold the standby, sleep, or deep-sleep state until software clears the peripheral control hold bit, pssr[ph]. software must clear this bit (by writing 0b1 to it) after the peripherals have been fully configured, as described in no te[1], but before the process actually uses them. gpios that are configured as inputs immediately after exiting sleep mode cannot be used until pssr[rdh] is cleared. [4] static memory control pins: during sleep mode, these pins can be programm ed either to drive the value in the power manager gpio sleep-state register (pgsr0/1/2/3) or to be pl aced in a hi-z (undriven) state. to select the hi-z state, software must set pcfr[fs]. if fs is not set, these pins function as described in note[3] during the transition to sleep mode. [5] pcmcia control pins: during sleep mode, these pins can be programmed ei ther to drive the value in the power manager gpio sleep-state register (pgsr0/1/2/3) or to be placed in a hi-z (undriven) state. to select the hi-z state, software must set pcfr[fp]. if fp is not set, these pins functi on as described in note[3] during the transition to sleep mode. [6] (reserved) [7] when the power manager overrides the gpio alternate fu nction, the power manager gpio sleep-state registers (pgsr0/1/2/3) and the pssr[rdh] bit are ignored. pullup and pulldown are disabled immediately after the power manager overrides the gpio function. [8] output functions during sleep mode [9] pull-up always enabled [10] (reserved) [11] pins do not function during sleep mode if the os timer is active [12] pins must be floated by software during sleep mode (floating does not happen automatically) [13] (reserved) [14] (reserved) [15] the pin is three-stateable (hi-z) based on the value of pcfr[fs]. there is no pgsr0/1/2/3 setting associated with the pin because it is not a gpio. [16] pwr_en goes high during reset, between the assertion of the reset pin and the de-assertion of internal reset within the pxa270 processor, after sys_en is driven high. [17] gpios 114 and115: the alternate function configuration of these pins is ignored when eit her pucr[usim114] or pucr[usim115] bits are set. setting these bits forces the usim enable signal onto these gpios. [18] when software sets the oscc[pio_en] or oscc[tout_en] bits, then any gpio alternate function setting applied to gpio<9> or gpio <10> is overridden with the clk_pio function on gpio<9> and clk_tout on gpio<10>.

6-2 electrical, mechanical, and thermal specification intel? pxa270 processor ac timing specifications 6.2 reset and power manager timing specifications the processor asserts the nreset_out pin in one of several different modes: ? power-on reset ? hardware reset ? watchdog reset ? gpio reset ? sleep mode ? deep-sleep mode the following sections give the timing and specifications for entry into and exit from these modes. 6.2.1 power-on timing specifications power-on reset begins when a power supply is detected on the backup battery pin, vcc_batt, after the processor has been powered off. a power-on reset is equivalent to a hardware reset, in that all units are reset to the same known state as with a hardware reset. a power-on reset is a complete and total reset that occurs only at initial power on. the external power-supply system must enable the power supplies for the processor in a specific sequence to ensure proper operation. figure 6-2 shows the timing diagram for a power-on reset sequence. table 6-2 details the timing. the sequence for power-on reset is as follows: 1. vcc_batt is established, then nreset should be de-asserted to initiate power-on reset. 2. pwr_out is asserted. the processor asserts nreset_out. 3. the external power-control subsystem de-asserts nbatt_fault to signal that the main battery is connected and not discharged. 4. the processor asserts the sys_en signal to enable the power supplies vcc_io, vcc_mem, vcc_bb, vcc_usb, and vcc_lcd. vcc_usim can be established at this time also but can be independently controlled through its own control signals. vcc_io must be established first. the other supplies can turn on in any order, but they must all be established within 125 milliseconds of the assertion of sys_en. 5. the processor asserts the pwr_en signal to enable the power supplies vcc_core, vcc_sram, and vcc_pll. these supplies can turn on in any order but must all be established within 125 milliseconds of the assertion of pwr_en. 6. the external power-control subsystem de-asserts nvdd_fault to signal that all system power supplies have been properly established. 7. the processor de-asserts nreset_out and ente rs run mode, executing code from the reset vector. note: nvdd_fault is sampled only when the sys_del and pwr_del timers have expired. refer to the intel? pxa27x processor family developer?s manual , ?initial power on? and ?deep-sleep exit states? for a state diagram.
