GPIO interrupt sense register

Offset: 0x404

Bits set to HIGH configure the corresponding pins to detect levels. Clearing a bit

configures the pin to detect edges. All bits are cleared by a reset.

GPIO interrupt both edges register

Offset: 0x408

When the corresponding bit in GPIO interrupt sense register (GPIO1_IS, …) is set to

detect edges, bits set to HIGH in GPIO interrupt both edges register (GPIO1_IBE, … )

configure the corresponding pin to detect both rising and falling edges, regardless of

the corresponding bit in the GPIO interrupt event register (GPIO1_IEV, …). Clearing a

bit configures the pin to be controlled by GPIO interrupt event register (GPIO1_IEV,

…). All bits are cleared by a reset.

7:0

GPIO interrupt event

00000000

0: on corresponding pin interrupt generation event is controlled

by GPIO interrupt event register (GPIO1_IEV, …).

1: both edges on corresponding pin trigger an interrupt.

Single edge determined by corresponding bit in GPIO interrupt

event register (GPIO1_IEV, …).
