Interrupt system
The STMPE1801 uses a highly flexible interrupt system. It allows the host system to
configure the type of system events that should result in an interrupt, and pinpoints the
source of interrupt by status registers. The INT pin can be configured as active high (a pull-
down resistor is required), or active low (a pull-up resistor is required). If INT pin is not in
use, it is necessary to pull INT pin to V
Once asserted, the INT pin would de-assert when a read is done to the corresponding bit
either in the INT_STA register or INT_STA_GPIO register.
