DESCRIPTION

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.

P1.0 to P1.3: 8-bit quasi-bidirectional I/O port lines;

CT0I to CT3I: Capture timer inputs for Timer 2.
