13.7.2 PTE1/RxD (Receive Data)
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).
13.8 I/O Registers
These I/O registers control and monitor SCI operation:
13.8.1 SCI Control Register 1

ENSCI — Enable SCI Bit

This read/write bit enables loop mode operation. In loop mode the PTE1/RxD pin is disconnected from
the SCI, and the transmitter output goes into the receiver input. Both the transmitter and the receiver
must be enabled to use loop mode. Reset clears the LOOPS bit.
This read/write bit enables the SCI and the SCI baud rate generator. Clearing ENSCI sets the SCTE
and TC bits in SCI status register 1 and disables transmitter interrupts. Reset clears the ENSCI bit.
1 = Loop mode enabled
0 = Normal operation enabled
1 = SCI enabled
0 = SCI disabled
