Transmit Interrupt Flag (Bit 1)
The Transmit Interrupt Flag is a read only bit that indicates a
byte mode transmit interrupt has triggered.
1: Indicates a byte mode transmit interrupt has triggered
0: Indicates a byte mode transmit interrupt has not triggered
SPI Interrupt Clear Register [0xC0D0] [W]
Register Description
The SPI Interrupt Clear register is a write-only register that
allows the SPI Transmit and SPI Transfer Interrupts to be
cleared.
Transmit Interrupt Clear (Bit 1)
The Transmit Interrupt Clear bit is a write-only bit that clears
the byte mode transmit interrupt. This bit is self-clearing.
1: Clear the byte mode transmit interrupt
0: No function
SPI CRC Control Register [0xC0D2] [R/W]
Register Description
The SPI CRC Control register provides control over the CRC
source and polynomial value.
CRC Mode (Bits [15:14)
The CRCMode field selects the CRC polynomial as defined in

Transfer Interrupt Flag (Bit 0)
The Transfer Interrupt Flag is a read only bit that indicates a
block mode interrupt has triggered.
1: Indicates a block mode interrupt has triggered
0: Indicates a block mode interrupt has not triggered
Transfer Interrupt Clear (Bit 0)
The Transfer Interrupt Clear bit is a write-only bit that will clear
the block mode interrupt. This bit is self clearing.
1: Clear the block mode interrupt
0: No function
Reserved
All reserved bits must be written as ‘0’.
