SPI Device Interrupt Status/Enable Registers
Interrupt Status Register (IPISR) This register holds the interrupt status flags for the Spi device. Interrupt Enable Register (IPIER) This register is used to enable interrupt sources for the Spi device. Writing a '1' to a bit in this register enables the corresponding Interrupt. Writing a '0' to a bit in this register disables the corresponding Interrupt. ISR/IER registers have the same bit definitions and are only defined once.
