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.
1:
Indicates a byte mode transmit interrupt triggered
0:
Indicates a byte mode transmit interrupt did not trigger
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
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
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’.
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
Table 112 on page 70
.
