P5.0–P5.7
Eight input channels to ADC (ADC0–ADC7)
Digital power supply: +5 V power supply pins during normal operation and power reduction modes. All pins
must be connected.
Digital ground: circuit ground potential. All pins must be connected.
Start ADC operation: Input starting analog to digital conversion triggered by a programmable edge (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 T3 watchdog timer and disable Power-down Mode.This pin must not
float.
