6.3.4.2.3 Interrupt Enable Register (IER)
This register enables four types of interrupts which independently activate the int signal and
set a value in the Interrupt Identification Register. Each of the four interrupt types can be
disabled by resetting the appropriate bit of the IER register. Similarly, by setting the appropriate
bits, selected interrupts can be enabled.
