Field Description
31–0
TXDATA
Transmit Data
Holds SPI data to be transferred according to the associated SPI command.
46.3.9 DSPI POP RX FIFO Register (SPIx_POPR)
POPR is used to read the RX FIFO. Eight- or sixteen-bit read accesses to the POPR have
the same effect on the RX FIFO as 32-bit read accesses. A write to this register will
generate a Transfer Error.
Addresses: SPI0_POPR is 4002_C000h base + 38h offset = 4002_C038h
SPI1_POPR is 4002_D000h base + 38h offset = 4002_D038h
