Description

SPI control register 2

Fields

SPC0

SPI pin control 0

0 (0): SPI uses separate pins for data input and data output (pin mode is normal). In master mode of operation: MISO is master in and MOSI is master out. In slave mode of operation: MISO is slave out and MOSI is slave in.

1 (1): SPI configured for single-wire bidirectional operation (pin mode is bidirectional). In master mode of operation: MISO is not used by SPI; MOSI is master in when BIDIROE is 0 or master I/O when BIDIROE is 1. In slave mode of operation: MISO is slave in when BIDIROE is 0 or slave I/O when BIDIROE is 1; MOSI is not used by SPI.
SPISWAI

SPI stop in wait mode

0 (0): SPI clocks continue to operate in wait mode

1 (1): SPI clocks stop when the MCU enters wait mode
RXDMAE

Receive DMA enable

0 (0): DMA request for receive is disabled and interrupt from SPRF is allowed

1 (1): DMA request for receive is enabled and interrupt from SPRF is disabled
BIDIROE

Bidirectional mode output enable

0 (0): Output driver disabled so SPI data I/O pin acts as an input

1 (1): SPI I/O pin enabled as an output
MODFEN

Master mode-fault function enable

0 (0): Mode fault function disabled, master SS pin reverts to general-purpose I/O not controlled by SPI

1 (1): Mode fault function enabled, master SS pin acts as the mode fault input or the slave select output
TXDMAE

Transmit DMA enable

0 (0): DMA request for transmit is disabled and interrupt from SPTEF is allowed

1 (1): DMA request for transmit is enabled and interrupt from SPTEF is disabled
SPMIE

SPI match interrupt enable

0 (0): Interrupts from SPMF inhibited (use polling)

1 (1): When SPMF is 1, requests a hardware interrupt
