Freescale Semiconductor
Port B shares two of its pins with the SCI module. The two SCI I/O pins
are:
The PTB1/TxD pin is the serial data output from the SCI transmitter. The
SCI shares the PTB1/TxD pin with port B. When the SCI is enabled, the
PTB1/TxD pin is an output regardless of the state of the DDRF1 bit in
data direction register B (DDRB).
The PTB0/RxD pin is the serial data input to the SCI receiver. The SCI
shares the PTB0/RxD pin with port B. When the SCI is enabled, the
PTB0/RxD pin is an input regardless of the state of the DDRB0 bit in data
direction register B (DDRB).
These I/O registers control and monitor SCI operation:
