Description
Port C. These pins are used for general-purpose I/O.
Transmit Data. This signal is the transmit output from the UART and IrDA.
Receive Data. This signal is the receive input for the UART and IrDA.
Clear To Send. This signal is the flow control input for the UART.
Driver Enable. This signal allows automatic control of external RS-485
drivers. This signal is approximately the inverse of the TXE (Transmit
Empty) bit in the UART Status 0 register. The DE signal may be used to
ensure the external RS-485 driver is enabled when data is transmitted by
the UART.
Timer Output 0–1. These signals are outputs from the timers.
Timer Complement Output 0–1. These signals are output from the timers
in PWM Dual Output mode.
counter inputs.
Port A. These pins are used for general-purpose I/O.
These pins are used for general-purpose I/O.
Port D. This pin is used for general-purpose output only.
Timer Input 0–1. These signals are used as the capture, gating and
