49.3.7 DSPI PUSH TX FIFO Register In Master Mode (SPIx_PUSHR)
PUSHR provides the means to write to the TX FIFO. Data written to this register is
transferred to the TX FIFO. Eight- or sixteen-bit write accesses to the PUSHR transfer all
32 register bits to the TX FIFO. The register structure is different in master and slave
modes. In master mode the register provides 16-bit command and 16-bit data to the TX
FIFO. In slave mode all 32 register bits can be used as data, supporting up to 32-bit SPI
frame operation.
Addresses: SPI0_PUSHR is 4002_C000h base + 34h offset = 4002_C034h
SPI1_PUSHR is 4002_D000h base + 34h offset = 4002_D034h
SPI2_PUSHR is 400A_C000h base + 34h offset = 400A_C034h

CONT
Continuous Peripheral Chip Select Enable
Description
Selects a Continuous Selection Format. The bit is used in SPI master mode. The bit enables the selected
PCS signals to remain asserted between transfers.
30–28
CTAS
0 Return PCSn signals to their inactive state between transfers.
1 Keep PCSn signals asserted between transfers.
Clock and Transfer Attributes Select.
Selects which CTAR register to use in master mode to specify the transfer attributes for the associated
SPI frame. In SPI slave mode, CTAR0 is used. See the Chip Configuration chapter to determine how
many CTAR registers this device has. You should not program a value in this field for a register that is not
present.
