9.4.74 PINCTRL Bank 1 Interrupt Polarity Register
The PINCTRL Bank 1 Interrupt Polarity Register selects the polarity for interrupt requests
for the pins in bank 1.
HW_PINCTRL_IRQPOL1: 0x1310
HW_PINCTRL_IRQPOL1_SET: 0x1314
HW_PINCTRL_IRQPOL1_CLR: 0x1318
HW_PINCTRL_IRQPOL1_TOG: 0x131C
This register selects the polarity for interrupt generation. Each pin in bank 1 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_IRQLEVEL1
(see above) appropriately.
