9.4.61 PINCTRL Bank 3 Interrupt Select Register
The Bank 3 Interrupt Select register selects which of the bank 3 pins may be used as interrupt
sources.
HW_PINCTRL_PIN2IRQ3: 0x1030
HW_PINCTRL_PIN2IRQ3_SET: 0x1034
HW_PINCTRL_PIN2IRQ3_CLR: 0x1038
HW_PINCTRL_PIN2IRQ3_TOG: 0x103C
As described earlier in this chapter, any digital I/O pin can be used as an interrupt source.
This register selects which pins in bank 3 can be used to generate interrupts. If the pin is
selected in this register by setting its bit to 1, then detection of the correct level or edge on
the pin (as chosen by the HW_PINCTRL_IRQLEVEL3 and HW_PINCTRL_IRQPOL3
registers) will set the corresponding bit in the HW_PINCTRL_IRQSTAT3 register. If the
pin is additionally enabled in the HW_PINCTRL_IRQEN0 register, then the interrupt will
be propagated to the interrupt collector as interrupt GPIO3. For example, if this register
contains 0x00000014, then pins GPIO3[2] and GPIO3[4] can be used as interrupt pins, and
no other pins in bank 0 will cause bits to be set in the HW_PINCTRL_IRQSTAT3 register.
