Receive Interrupt Flag (Bit 2)
The Receive Interrupt Flag is a read only bit that indicates if a
byte mode receive interrupt triggered.
1: Indicates a byte mode receive interrupt triggered
0: Indicates a byte mode receive interrupt did not trigger
Transmit Interrupt Flag (Bit 1)
The Transmit Interrupt Flag is a read only bit that indicates a byte
mode transmit interrupt triggered.
SPI Interrupt Clear Register [0xC0D0] [W]
Table 110. SPI Interrupt Clear Register
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]
Table 111. SPI CRC Control Register
Register Description
The SPI CRC Control register provides control over the CRC
source and polynomial value.

Transfer Interrupt Flag (Bit 0)
The Transfer Interrupt Flag is a read only bit that indicates a
block mode interrupt triggered.
1: Indicates a block mode interrupt triggered
0: Indicates a block mode interrupt did not trigger
Transfer Interrupt Clear (Bit 0)
The Transfer Interrupt Clear bit is a write only bit that clears the
block mode interrupt. This bit is self clearing.
1: Clear the block mode interrupt
0: No function
Reserved
Write all reserved bits with ’0’.
