30.11.2.8 DSPI Transmit FIFO Registers 0–3 (DSPI_TXFR0–DSPI_TXFR3)
The DSPI_TXFR0 - DSPI_TXFR3 registers provide visibility into the TX FIFO for debugging purposes.
Each register is an entry in the TX FIFO. The registers are read-only and cannot be modified. Reading the
DSPI_TXFRx registers does not alter the state of the TX FIFO.
Address: DSPI_BASE + 0x38
