Here x indicates the specific GPIO port pin number (0 through 7). PAD7I and PAD0I have
interrupt sources other than Port A and Port D as selected by the Port A Irq Mux registers.
PAD7I is configured to provide the comparator interrupt. PAD0I is configured to provide
the OCD interrupt.
These bits are set any time the selected port is toggled. The setting of these bits are not
affected by the associated interrupt enable bits.
The interrupt request 2 (IRQ2) register (see
vectored and polled interrupts. When a request is presented to the interrupt controller, the
corresponding bit in the IRQ2 register becomes 1. If interrupts are globally enabled
(vectored interrupts), the interrupt controller passes an interrupt request to the ZNEO
CPU. If interrupts are globally disabled (polled interrupts), the ZNEO CPU reads the
interrupt request 1 register to determine, if any interrupt requests are pending. Writing 1 to
the bits in this register clears the interrupt. The bits of this register are set by writing 1 to
the interrupt request 2 set regsiter (IRQ2SET) at address FF_E039H.
PWMTI—PWM Timer Interrupt Request
0 = No interrupt request is pending for the PWM timer.
1 = An interrupt request from the PWM timer is awaiting service. Writing 1 to this bit
Resets it to 0.
