Bits [7:0] SC_DATA: Transmit and receive data register. Writing to this register adds a byte to the transmit
SPI master mode registers
Serial data register (SCx_DATA)
Address offset: 0xC83C (SC1_DATA) and 0xC03C (SC2_DATA)
Reset value:
SPI configuration register (SCx_SPICFG)
Address offset: 0xC858 (SC1_SPICFG) and 0xC058 (SC2_SPICFG)
Reset value:
Bit 5 SC_SPIRXDRV: Receiver-driven mode selection bit (SPI master mode only). Clear this bit to
Bit 4 SC_SPIMST: Set this bit to put the SPI in master mode, clear this bit to put the SPI in slave
Bit 3 SC_SPIRPT: This bit controls behavior on a transmit buffer underrun condition in slave mode.
Bit 2 SC_SPIORD: This bit specifies the bit order in which SPI data is transmitted and received.

FIFO. Reading from this register takes the next byte from the receive FIFO and clears the
overrun error bit if it was set.
In UART mode (SC1 only), reading from this register loads the UART status register with the
parity and frame error status of the next byte in the FIFO, and clears these bits if the FIFO is
now empty.
initiate transactions when transmit data is available. Set this bit to initiate transactions when the
receive buffer (FIFO or DMA) has space.
mode.
Clear this bit to send the BUSY token (0xFF) and set this bit to repeat the last byte. Changes to
this bit take effect when the transmit FIFO is empty and the transmit serializer is idle.
0: Most significant bit first.
