9.4.59 PINCTRL Bank 1 Interrupt Select Register
The Bank 1 Interrupt Select register selects which of the bank 1 pins may be used as interrupt
sources.
HW_PINCTRL_PIN2IRQ1: 0x1010
HW_PINCTRL_PIN2IRQ1_SET: 0x1014
HW_PINCTRL_PIN2IRQ1_CLR: 0x1018
HW_PINCTRL_PIN2IRQ1_TOG: 0x101C
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 1 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_IRQLEVEL1 and HW_PINCTRL_IRQPOL1
registers) will set the corresponding bit in the HW_PINCTRL_IRQSTAT1 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 GPIO1. For example, if this register
contains 0x00000014, then pins GPIO1[2] and GPIO1[4] can be used as interrupt pins, and
no other pins in bank 0 will cause bits to be set in the HW_PINCTRL_IRQSTAT1 register.
