14.2.3. Interrupts

There are five interrupts generated by the PrimeCell SSP. Four of these are individual, maskable, active HIGH interrupts:

SSPRXINTR

PrimeCell SSP receive FIFO service interrupt request.

SSPTXINTR

PrimeCell SSP transmit FIFO service interrupt request.

SSPRORINTR

PrimeCell SSP receive overrun interrupt request.

SSPRTINTR

PrimeCell SSP time out interrupt request.

The fifth is a combined single interrupt SSPINTR.

Note

Only the combined interrupt is connected to the interrupt controller. VIC interrupt line 11 is used for the SSP interrupt.

The status of the individual interrupt sources can be read from SSPRIS and SSPMIS registers.
