Table 4−12. GPIO Interrupt Event Type Register
BIT FIELD NAME TYPE DESCRIPTION
7−4 RSVD R Reserved. Bits 7−4 return 0s when read.
3 GPIO3INTYPE RW
GPIO3 interrupt type.
0 = Bit 28 (IntGPIO3) in the interrupt event register (see Section 5.1) is set when GPIO3 input is
low (default)
1 = Bit 28 (IntGPIO3) in the interrupt event register (see Section 5.1) is set when GPIO3 input
changes state
2 GPIO2INTYPE RW
GPIO2 interrupt type.
0 = Bit 27 (IntGPIO2) in the interrupt event register (see Section 5.1) is set when GPIO2 input is
low (default)
1 = Bit 27 (IntGPIO2) in the interrupt event register (see Section 5.1) is set when GPIO2 input
changes state
1−0 RSVD R Reserved. Bits 1−0 return 0s when read.
