Receive Bit Length (Bits [2:0])
The Receive Bit Length field controls whether a full byte or partial byte will be received. If Receive Bit Length is ‘000’ then a full
byte will be received. If Receive Bit Length is ‘001’ to ‘111’, then the value indicates the number of bits that will be received.
SPI Interrupt Enable Register [0xC0CC] [R/W]
Register Description
The SPI Interrupt Enable register controls the SPI port.
Receive Interrupt Enable (Bit 2)
The Receive Interrupt Enable bit enables or disables the byte
mode receive interrupt (RxIntVal).
1: Enable byte mode receive interrupt
0: Disable byte mode receive interrupt
Transmit Interrupt Enable (Bit 1)
The Transmit Interrupt Enable bit enables or disables the byte
mode transmit interrupt (TxIntVal).
SPI Status Register [0xC0CE] [R]
Register Description
The SPI Status register is a read only register that provides
status for the SPI port.
FIFO Error Flag (Bit 7)
The FIFO Error Flag bit is a read only bit that indicates if a FIFO
error occurred. When this bit is set to ‘1’ and the Transmit
Empty bit of the SPI Control register is set to ‘1’, then a Tx FIFO
underflow has occurred. Similarly, when set with the Receive
Full bit of the SPI Control register, a Rx FIFO overflow has

Transfer Interrupt Enable (Bit 0)
The Transfer Interrupt Enable bit enables or disables the block
mode interrupt (XfrBlkIntVal).

Receive Interrupt Flag (Bit 2)
The Receive Interrupt Flag is a read only bit that indicates if a
byte mode receive interrupt has triggered.
1: Indicates a byte mode receive interrupt has triggered
0: Indicates a byte mode receive interrupt has not triggered
