Power supply, digital part (+5 V). Power supply pins during normal operation and
power reduction modes.
Start ADC operation: Input starting analog-to-digital conversion (ADC operation can
also be started by software). This pin must not float.
Pulse Width Modulation output 0.
Pulse Width Modulation output 1.
Enable Watchdog Timer: enable for Watchdog Timer and disable Power-down mode.
This pin must not float.
P4.0 to P4.5: 8-bit quasi-bidirectional I/O port lines;
CMSR0 to CMSR5: Compare and Set/Reset outputs for Timer T2.
P4.6 to P4.7: 8-bit quasi-bidirectional I/O port lines;
CMT0 to CMT1: Compare and toggle outputs for Timer T2.
Reset: Input to reset the P8x562; also generated when the Watchdog Timer overflows.
