Table 23-4. Available Interrupt Vectors and Sources
Name Vector Description
SPI SPI interrupt
When an interrupt condition occurs, the corresponding interrupt flag is set in the Interrupt Flags register of
the peripheral (peripheral.INTFLAGS).
An interrupt source is enabled or disabled by writing to the corresponding enable bit in the peripheral's
Interrupt Control register (peripheral.INTCTRL).
An interrupt request is generated when the corresponding interrupt source is enabled and the interrupt
flag is set. The interrupt request remains active until the interrupt flag is cleared. See the peripheral's
INTFLAGS register for details on how to clear interrupt flags.
