General Purpose I/O (GPIO)
Table 22-5
22.3.4
The GPIO interrupt event register (GPIER), shown in
caused an interrupt. Each bit in GPIER, corresponds to an interrupt source. GPIER bits are cleared by
writing ones. However, writing zero has no effect.
Table 22-6
22.3.5
The GPIO interrupt mask register (GPIMR), shown in
individual ports. When a masked interrupt request occurs, the corresponding GPIER bit is set, regardless
of the GPIMR state. When one or more non-masked interrupt events occur, the GPIO module issues an
interrupt to the on chip interrupt controller.

GPIO Interrupt Event Register (GPIER)
GPIO Interrupt Mask Register (GPIMR)
Data. Write data is latched and presented on external signals if GPDIR has configured the port as an output.
Read operation always returns the data at the signal. Bits D0–D15 correspond to signals GPIO[0:15]. Bits
D16–D31 are unused.
Interrupt events. Indicates whether an interrupt event occurred on the corresponding GPIO signal. Bits
D0–D15 correspond to signals GPIO[0:15]. Bits D16–D31 are unused.
0 No interrupt event occurred on the corresponding GPIO signal.
1 Interrupt event occurred on the corresponding GPIO signal.
