8.10 Interrupt Structure
The interrupt structure is designed to efficiently guide the user to the source of an interrupt. The status bits in the
global interrupt status register (GLOBAL.ISR) are read to determine if the interrupt source comes from a global
event, such as a one-second timer interrupt, or one of the ports. If the interrupt source is a global event, the global
status register is read (GLOBAL.SRL) to determine the source. If the interrupt source is a port, the port interrupt
status register (PORT.ISR) is read to determine if the interrupt source comes from a port event, such as a
performance monitor update interrupt, or one of the functional blocks inside the port. If the interrupt source is a port
event, the port status register is read (PORT.SRL) to determine the source. If the interrupt source is from a
functional block inside the port, the associated block's status register is read to determine the source. The source
of an interrupt can be determined by reading no more than three 16-bit registers.
Once the interrupt source has been determined, the interrupt can be cleared by either reading or writing the latched
status register (see Section 8.8.5). An alternate method for clearing an interrupt is to disable the interrupt at the bit,
block, port, or global level by writing a zero to the associated interrupt enable bit. Note: Disabling the interrupt at
the block, port, or global level disables all interrupts sources at or below that level.
