MOTOROLA
The PTE0/SCTxD pin is the serial data output from the SCI transmitter.
The SCI shares the PTE0/SCTxD pin with port E. When the SCI is
enabled, the PTE0/SCTxD pin is an output regardless of the state of the
DDRE2 bit in data direction register E (DDRE).
The PTE1/SCRxD pin is the serial data input to the SCI receiver. The
SCI shares the PTE1/SCRxD pin with port E. When the SCI is enabled,
the PTE1/SCRxD 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:
