Table 129. GPIO interrupt sense register (IS - address 0x5000 0024 (GPIO0), 0x5001 0024
Table 130. GPIO interrupt both edges sense register (IBE - address 0x5000 0028 (GPIO0),
Table 131. GPIO interrupt event register (IEV - address 0x5000 002C (GPIO0), 0x5001 002C
Bits set to HIGH in the IE register allow the corresponding pins to trigger their individual
interrupts and the combined INTR line. Clearing a bit disables interrupt triggering on that
pin.

Selects interrupt on pin PIOn_x to be triggered on both
edges.
0 = Interrupt on pin PIOn_x is controlled through register IEV.
1 = Both edges on pin PIOn_x trigger an interrupt.
Description
Selects GPIO pin PIOn_x as input or output.
0 = Pin PIOn_x is configured as input.
1 = Pin PIOn_x is configured as output.
Description
Selects interrupt on pin PIOn_x as level or edge sensitive.
0 = Interrupt on pin PIOn_x is configured as edge sensitive.
1 = Interrupt on pin PIOn_x is configured as level sensitive.
Description
Selects interrupt on pin PIOn_x to be triggered rising or
falling edges.
0 = Depending on setting in register IS, falling edges or
LOW level on pin PIOn_x trigger an interrupt.
1 = Depending on setting in register IS, rising edges or
HIGH level on pin PIOn_x trigger an interrupt.
