Programmable Registers
9.4.68 PINCTRL Bank 0 Interrupt Level/Edge Register
The PINCTRL Bank 0 Interrupt Level/Edge Register selects level or edge sensitivity for
interrupt requests for the pins in bank 0.
HW_PINCTRL_IRQLEVEL0: 0x1200
HW_PINCTRL_IRQLEVEL0_SET: 0x1204
HW_PINCTRL_IRQLEVEL0_CLR: 0x1208
HW_PINCTRL_IRQLEVEL0_TOG: 0x120C
This register selects level or edge detection for interrupt generation. Each pin in bank 0 that
is configured for interrupt generation can be independently set to interrupt on low level,
high level, rising edge, or falling edge by setting bits in this register and
HW_PINCTRL_IRQPOL0 (see below) appropriately.
