Serial Communications Interface (SCI) Module
SBR12:SBR0 — Baud Rate Modulo Divisor
11.10.2 SCI x Control Register 1 (SCIxC1)
This read/write register is used to control various optional features of the SCI system.
LOOPS — Loop Mode Select
178
These 13 bits are referred to collectively as BR, and they set the modulo divide rate for the SCI baud
rate generator. When BR = 0, the SCI baud rate generator is disabled to reduce supply current. When
BR = 1 to 8191, the SCI baud rate = BUSCLK/(16×BR).
Selects between loop back modes and normal 2-pin full-duplex modes. When LOOPS = 1, the
transmitter output is internally connected to the receiver input.
1 = Loop mode or single-wire mode where transmitter outputs are internally connected to receiver
0 = Normal operation — RxD1 and TxD1 use separate pins.
