11.13.21 PIR3

Peripheral Interrupt Request Register 3

Note:

Interrupt flag bits get set when an interrupt condition occurs, regardless of the state of its corresponding enable bit, or the global enable bit. User software must ensure the appropriate interrupt flag bits are clear prior to enabling an interrupt.
SPI1IF is a read-only bit. To clear the interrupt condition, all bits in the SPI1INTF register must be cleared.
SPI1TXIF and SPI1RXIF are read-only bits and cannot be set/cleared by software.
