Programmable Registers
9.4.77 PINCTRL Bank 4 Interrupt Polarity Register
The PINCTRL Bank 4 Interrupt Polarity Register selects the polarity for interrupt requests
for the pins in bank 4.
HW_PINCTRL_IRQPOL4: 0x1340
HW_PINCTRL_IRQPOL4_SET: 0x1344
HW_PINCTRL_IRQPOL4_CLR: 0x1348
HW_PINCTRL_IRQPOL4_TOG: 0x134C
This register selects the polarity for interrupt generation. Each pin in bank 4 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_IRQLEVEL4
(see above) appropriately.
