The PTE0/TxD pin is the serial data output from the SCI transmitter. The
SCI shares the PTE0/TxD pin with port E. When the SCI is enabled, the
PTE0/TxD pin is an output regardless of the state of the DDRE2 bit in
data direction register E (DDRE).
The PTE1/RxD pin is the serial data input to the SCI receiver. The SCI
shares the PTE1/RxD pin with port E. When the SCI is enabled, the
PTE1/RxD pin is an input regardless of the state of the DDRE1 bit in data
direction register E (DDRE).
The following I/O registers control and monitor SCI operation:
