Power Pin Treatment
Connect the IC as shown below to minimize the noise input to the VDD1 pin. Be sure to electrically short the VSS1, VSS2, and VSS3 pins. Example 1: When the microcontroller is in the backup state in the HOLD mode, the power to sustain the high level of output ports is supplied by their backup capacitors.

USB Reference Power Option
When a voltage 4.5 to 5.5V is supplied to VDD1 and the internal USB reference voltage circuit is activated, the reference voltage for USB port output is generated. The active/inactive state of reference voltage circuit can be switched by the option select. The procedure for marking the option selection is described below.
(1) Option select USB Regulator USB Regulator at HOLD mode USB Regulator at HALT mode Reference voltage circuit state Normal state HOLD mode HALT mode USE USE USE active active active (2) USE NONUSE NONUSE active inactive inactive (3) USE NONUSE USE active inactive active (4) NONUSE NONUSE NONUSE inactive inactive inactive
* When the USB reference voltage circuit is made inactive, the level of the reference voltage for USB port output is equal to VDD1. * Selection (2) or (3) can be used to set the reference voltage circuit inactive in HOLD or HALT mode. * When the reference voltage circuit is activated, the current drain increase by approximately 100A compared with when the reference voltage circuit is inactive. Example 1: VDD1=VDD2=3.3V * Inactivating the reference voltage circuit (selection (4)). * Connecting VDD3 to VDD1 and VDD2.

D+ 27 to 33 5pF
Note: It's necessary to adjust the Circuit Constant of the USB Port Peripheral Circuit each mounting board. Make the D+ Pull-up resistors available to control on/off according to the Vbus.
