bit 2

Unimplemented: Read as ‘0’

bit 1

SPITBF: SPIx Transmit Buffer Full Status bit

1 = SPIxTXB is full

0 = SPIxTXB not full

Standard Buffer Mode:

Automatically set in hardware when SPIxBUF is written, loading SPIxTXB. Automatically cleared in

hardware when SPIx transfers data from SPIxTXB to SPIxTXSR.

Enhanced Buffer Mode:

Indicates TXELM<5:0> = 6’b111111.

bit 0

SPIRBF: SPIx Receive Buffer Full Status bit

1 = SPIxRXB is full

0 = SPIxRXB is not full

Standard Buffer Mode:

Automatically set in hardware when SPIx transfers data from SPIxRXSR to SPIxRXB. Automatically

cleared in hardware when SPIxBUF is read from, reading SPIxRXB.

Enhanced Buffer Mode:

Indicates RXELM<5:0> = 6’b111111.

SPIxSTATL: SPIx STATUS REGISTER LOW (CONTINUED)

Note 1:

SPITUR is cleared when SPIEN = 0. When IGNTUR = 1, SPITUR provides dynamic status of the Transmit

Underrun condition, but does not stop RX/TX operation and does not need to be cleared by software.
