STMPE821

Interrupt controller module

21/55

INT_EN

Interrupt enable register

Address:

0x09

Type:

R/W

Reset:

0x00

Description:

This register is used to enable the interruption from a system related interrupt source

to the host. Writing ‘1’ in this register enables the corresponding interrupt event to

generate interrupt signal at the INT pin. Note that even if the interrupt is not enabled,

an interrupt event will still be reflected in the interrupt status register.
