2.5.4
This section describes the interrupts generated by the PIM and their individual sources. Vector addresses
and interrupt priorities are defined at MCU level.
2.5.4.1
The XIRQ pin allows requesting non-maskable interrupts after reset initialization. During reset, the X bit
in the condition code register is set and any interrupts are masked until software enables them.
The IRQ pin allows requesting asynchronous interrupts. The interrupt input is disabled out of reset. To
enable the interrupt the IRQCR[IRQEN] bit must be set and the I bit cleared in the condition code register.
The interrupt can be configured for level-sensitive or falling-edge-sensitive triggering. If IRQCR[IRQEN]
is cleared while an interrupt is pending, the request will deassert.
