GENERAL DESCRIPTION
The Z86C15 Keyboard Controller is a full-featured member of the Z8 (R) microcontroller family offering a unique register-to-register architecture that avoids accumulator bottlenecks and is more code efficient than RISC processors. For applications demanding powerful I/O capabilities, the Z86C15 provides 32 pins dedicated to input and output. These lines are grouped into four ports, each port consisting of eight lines, and are configurable under software control to provide timing, status signals, and serial or parallel I/O ports. Two on-chip counter/timers, with a large number of userselectable modes, are available to relieve the system of administering real-time tasks, such as counting/timing and I/O datacommunications. Six different internal or external interrupt sources are maskable and prioritized so a vectored address is provided for efficient interrupt subroutine handling and multitasking functions. The Z86C15 achieves low-EMI by means of several modifications in the output drivers and clock circuitry of the device. By means of an expanded register file, the designer has access to three additional system control registers that provide extra peripheral devices, I/O ports, and register addresses (see Functional Block Diagram).
Notes: All Signals with a preceding front slash, "/", are active Low, e.g., B//W (WORD is active Low); /B/W (BYTE is active Low, only). Power connections follow conventional descriptions below: Connection Power Ground Circuit VCC GND Device VDD VSS
