Description

SC_RATEEXP

[3:0]

The exponential component (EXP) of the clock rate in the equation:

rate = 12MHz / ( (LIN + 1) * (2^EXP) )

8.4

SPI - Slave Mode

Both SC1 and SC2 SPI controllers include a SPI slave controller with these features:

Full duplex operation

Up to 5 Mbps data transfer rate

Programmable clock polarity and clock phase

Selectable data shift direction (either LSB or MSB first)

Slave select input

8.4.1

GPIO Usage

The SPI slave controller uses four signals:

MOSI (Master Out, Slave In) – inputs serial data from the master

MISO (Master In, Slave Out) – outputs serial data to the master

SCLK (Serial Clock) – clocks data transfers on MOSI and MISO

nSSEL (Slave Select) – enables serial communication with the slave
