ISGPIOR

Interrupt status GPIO mask register

Address:

0x0A, 0x0B

Type:

RW

Reset:

0

Description:

Interrupt status GPIO register (ISGPIOR)

The ISGPIOR register monitors the status of the interruption from a particular GPIO

pin interrupt source to the host. Regardless of the IEGPIOR bits are enabled or not,

the ISGPIOR bits are still updated. The ISG[15:0] bits are the interrupt status bits

corresponding to the GPIO[15:0] pins.
