Enhanced Serial Communications Interface (ESCI) Module
13.7.2 ESCI Receive Data (RxD)
The RxD pin is the serial data input to the ESCI receiver. When the ESCI is enabled, the RxD pin becomes
an input.
13.8 Registers
The following registers control and monitor operation of the ESCI:
13.8.1 ESCI Control Register 1
ESCI control register 1 (SCC1):

This read/write bit enables loop mode operation. In loop mode the RxD pin is disconnected from the
ESCI, and the transmitter output goes into the receiver input. Both the transmitter and the receiver
must be enabled to use loop mode.
1 = Loop mode enabled
0 = Normal operation enabled
