8.2
Interrupt status GPIO register (ISGPIOR)
ISGPIOR register monitors the status of the interruption from a particular GPIO pin interrupt
source to the host. Regardless whether the IEGPIOR bits are enabled or not, the ISGPIOR
bits are still updated. The ISG[9:0] bits are the interrupt status bits correspond to the
GPIO[7:0] pins.
8.3
GPIO controller
A total of 8 GPIOs are available in the STMPE801 port expander IC. The GPIO controller
contains the registers that allow the host system to configure each of the pins as input or
output. Unused GPIOs should be configured as outputs to minimize the power consumption.
A group of registers are used to control the exact function of each of the 8 GPIO. The
registers and their respective address is listed in the following table.
