USART1 and 2 Transmit Data.
USART1 and 2 Receive Data.
USART Serial Clock. May be used as input or output
when the USART is configured to operate in its
synchronous mode of operation.
Telephone Line Ring. Detection of a pulse train on
this pin is a wake-up event that can activate the
power-up request (PWUREQ). The pin has a
Schmitt Trigger input buffer, powered by V
Ring Indicator. When low, it indicates that a
telephone ring signal has been received by the
modem. Ring signals are monitored during Power-
Off for wake-up event detection.
Timer Pin A for Timers 2 and 1.
Timer Pin B for Timers 2 and 1.
PWM Output 7-0.
