13.4.3.9 SPI Masked Interrupt Status Register

The following table describes the Masked Interrupt Status (MIS) register. It is a read-only register. On a read, this register gives the current masked status value of the corresponding interrupt. A write has no effect.

Table 13-18. MIS
Bit Number Name R/W Reset Value Description
[31:6] Reserved R/W 0 Software should not rely on the value of a reserved bit. To provide compatibility with future products, the value of a reserved bit should be preserved across a read-modify-write operation.
5 SSEND R Indicates that SPI_X_SS[x] has gone inactive. When this is high, the interrupt is active.
4 CMDINT R Indicates that the number of frames set by the CMDSIZE register has been received as a single packet of frames (SPI_X_SS[x] held active). When this is high, the interrupt is active.
3 TXCHUNDDMSKINT R 0 Masked interrupt status. Reading this returns interrupt status.

Masked interrupt status = Raw interrupt status and interrupt mask
(Table 13-9 register)

MIS = RIS and Table 13-9[7:4]

Masked status of transmit channel under-run TXCHUNDMSKINT=TXCHUNDRINT and INTTXUNRRUN

2 RXCHOVRFMSKINT R 0 Masked status of receive channel overflow.

RXCHOVRFMSKINT = RXCHOVRFINT and INTRXOVRFLO

1 RXRDYMSKINT R 0 Masked status of receive data ready (data received in FIFO).

RXRDYMSKINT = RXRDY and INTTXDATA

0 TXDONEMSKINT R 0 Masked status of transmit done (data shifted out)

TXDONEMSKINT = TXDONE and INTRXDATA
