Serial Communications Interface (SCI)
18.7 I/O Signals
Port E shares two of its pins with the SCI module. The two SCI I/O pins are:
18.7.1 PTE0/SCTxD (Transmit Data)
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).
18.7.2 PTE1/SCRxD (Receive Data)
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).
18.8 I/O Registers
The following I/O registers control and monitor SCI operation:
18.8.1 SCI Control Register 1
