Interrupt system
STMPE2403 uses a highly flexible interrupt system. It allows host system to configure the
type of system events that should result in an interrupt, and pinpoints the source of interrupt
by status register. The INT pin could be configured as ACTIVE HIGH, or ACTIVE LOW.
Once asserted, the INT pin would de-assert only if the corresponding bit in the Interrupt
Status register is cleared.
