Technical Data
252
The PE1/RxD pin is the serial data input to the SCI receiver. The SCI
shares the PE1/RxD pin with port E. When the SCI is enabled, the
PE1/RxD pin is an input regardless of the state of the DDRE1 bit in data
direction register E (DDRE).
These I/O registers control and monitor SCI operation:
