Chapter 6: LPC13xx Interrupt controller
6.6.2 Interrupt Set-Enable Register 1
The ISER1 register allows enabling the second group of peripheral interrupts, or for
reading the enabled state of those interrupts. Disabling interrupts is done through the
ICER0 and ICER1 registers (Section 6.6.3
and Section 6.6.4).
The bit description is as follows for all bits in this register:
Write — Writing 0 has no effect, writing 1 enables the interrupt.
Read — 0 indicates that the interrupt is disabled, 1 indicates that the interrupt is enabled.
