Programmable Registers
9.4.66 PINCTRL Bank 3 Interrupt Mask Register (HW_PINCTRL_IRQEN3)
The PINCTRL Bank 3 Interrupt Mask Register contains interrupt enable masks for the pins
in bank 3.
HW_PINCTRL_IRQEN3: 0x1130
HW_PINCTRL_IRQEN3_SET: 0x1134
HW_PINCTRL_IRQEN3_CLR: 0x1138
HW_PINCTRL_IRQEN3_TOG: 0x113C
As described earlier in this chapter, any digital I/O pin can be used as an interrupt source.
This register masks the interrupt sources from the pins in bank 3. If a bit is set in this register
and the same bit is set in HW_PINCTRL_IRQSTAT3, an interrupt will be propagated to
the interrupt collector as interrupt GPIO3. For example, if this register contains 0x00000014,
then only bits 2 and 4 in HW_PINCTRL_IRQSTAT3 (corresponding to pins GPIO3[2] and
GPIO3[4]) will cause interrupts from bank 3.

Empty Description.
Each bit in this register corresponds to one of the 28 pins in bank 2:
1= Enable interrupts from the corresponding bit in HW_PINCTRL_IRQSTAT2.
0= Disable interrupts from the corresponding bit in HW_PINCTRL_IRQSTAT2.
