Description
Loop Back Mode.
During normal operation.
Serial input is taken from the serial output (MOSI or MISO)
rather than the serial input pin (MISO or MOSI
respectively).
SPI Enable.
The SPI controller is disabled.
The SPI controller will interact with other devices on the
serial bus. Software should write the appropriate control
information to the other SPI/SSP registers and interrupt
controller registers, before setting this bit.
Master/Slave Mode.This bit can only be written when the
SSE bit is 0.
The SPI controller acts as a master on the bus, driving the
SCLK, MOSI, and SSEL lines and receiving the MISO line.
The SPI controller acts as a slave on the bus, driving MISO
line and receiving SCLK, MOSI, and SSEL lines.
Slave Output Disable. This bit is relevant only in slave
mode (MS = 1). If it is 1, this blocks this SPI controller from
driving the transmit data line (MISO).
Reserved, user software should not write ones to reserved
bits. The value read from a reserved bit is not defined.
