SPI Interrupt Enable read and Set. A complete value may be read from this register. Writing a 1 to any implemented bit position causes that bit to be set.
| RXRDYEN | Determines whether an interrupt occurs when receiver data is available. 0 (NO_INTERRUPT_WILL_BE): No interrupt will be generated when receiver data is available. 1 (AN_INTERRUPT_WILL_BE): An interrupt will be generated when receiver data is available in the RXDAT register. |
| TXRDYEN | Determines whether an interrupt occurs when the transmitter holding register is available. 0 (NO_INTERRUPT_WILL_BE): No interrupt will be generated when the transmitter holding register is available. 1 (AN_INTERRUPT_WILL_BE): An interrupt will be generated when data may be written to TXDAT. |
| RXOVEN | Determines whether an interrupt occurs when a receiver overrun occurs. This happens in slave mode when there is a need for the receiver to move newly received data to the RXDAT register when it is already in use. The interface prevents receiver overrun in Master mode by not allowing a new transmission to begin when a receiver overrun would otherwise occur. 0 (NO_INTERRUPT_WILL_BE): No interrupt will be generated when a receiver overrun occurs. 1 (AN_INTERRUPT_WILL_BE): An interrupt will be generated if a receiver overrun occurs. |
| TXUREN | Determines whether an interrupt occurs when a transmitter underrun occurs. This happens in slave mode when there is a need to transmit data when none is available. 0 (NO_INTERRUPT_WILL_BE): No interrupt will be generated when the transmitter underruns. 1 (AN_INTERRUPT_WILL_BE): An interrupt will be generated if the transmitter underruns. |
| SSAEN | Determines whether an interrupt occurs when the Slave Select is asserted. 0 (NO_INTERRUPT_WILL_BE): No interrupt will be generated when any Slave Select transitions from deasserted to asserted. 1 (AN_INTERRUPT_WILL_BE): An interrupt will be generated when any Slave Select transitions from deasserted to asserted. |
| SSDEN | Determines whether an interrupt occurs when the Slave Select is deasserted. 0 (NO_INTERRUPT_WILL_BE): No interrupt will be generated when all asserted Slave Selects transition to deasserted. 1 (AN_INTERRUPT_WILL_BE): An interrupt will be generated when all asserted Slave Selects transition to deasserted. |
| RESERVED | Reserved. Read value is undefined, only zero should be written. |
