Receive Timeout. If set and the FIFO is not empty, an IRQ will be generated if 128 HCLK Cycles Pass before
the DATA register is read.
FIFO Overrun Interrupt. Indicated that the FIFO has been written to while full. Write a one to the SCT Clear
address to reset this interrupt request status bit.
FIFO Overrun Interrupt Enable. If set, an IRQ will be generated if the FIFO is written to while full.
DMA Enable. This signal enables DMA request and DMA Command End signals to be asserted.
Reserved
Slave Output Disable. 0: SSP can drive MISO in Slave Mode. 1: SSP does not drive MISO in slave mode.
Serial Clock Phase. For SPI mode only.
Serial Clock Polarity. In SD/MMC mode, 0: Command and TX data change after rising edge of SCK. In SPI
mode, 0: Steady-state '0' on SCK when data is not being transferred. 1: Steady-state '1' on SCK when data
is not being transferred.
Slave Mode. 0: SSP is in Master Mode. 1: SSP is in Slave Mode. Set to zero for SD/MMC modes.
Word Length in bits per word. 0x0 to 0x2 are Reserved and Undefined. 0x3 is 4-bits per word...0xF is 16-bits
per word. Always use 8 bits per word in SD/MMC Modes.

Operating Mode. 0x0 = Motorola and Winbond SPI Mode, 0x1 = TI syncronous serial mode, 0x3 = SD/MMC
Card. All other values are undefined. Before changing ssp_mode, a softreset must be issued to clear the
FIFO.
