Programmable Registers
9.4.75 PINCTRL Bank 2 Interrupt Polarity Register
The PINCTRL Bank 2 Interrupt Polarity Register selects the polarity for interrupt requests
for the pins in bank 2.
HW_PINCTRL_IRQPOL2: 0x1320
HW_PINCTRL_IRQPOL2_SET: 0x1324
HW_PINCTRL_IRQPOL2_CLR: 0x1328
HW_PINCTRL_IRQPOL2_TOG: 0x132C
This register selects the polarity for interrupt generation. Each pin in bank 2 which is
configured for interrupt generation can be independently set to interrupt on low level, high
level, rising edge, or falling edge by setting this register and HW_PINCTRL_IRQLEVEL2
(see above) appropriately.
