13.4.18 Pin interrupt select register 1
Table 130. Pin interrupt select register 0 (PINTSEL0, address 0x4008 6E00) bit description
This register selects one GPIO pin from all GPIO pins on all ports as the source for pin
interrupts 4 to 7.
As an example, for pin interrupt 4, INTPIN4 = 0xA selects GPIO pin GPIO0[10] if
PORTSEL1 = 0 or pin GPIO1[10] if PORTSEL = 1. Each pin interrupt must be enabled in
the NVIC using interrupt slots 32 to 39.
To enable each pin interrupt and configure its edge or level sensitivity, use the GPIO pin
interrupt registers (see
Table 131. Pin interrupt select register 1 (PINTSEL1, address 0x4008 6E04) bit description
