6.5.1 Interrupt Set-Enable Register 0 register (ISER0 - 0xE000 E100)
The ISER0 register allows enabling the first 32 peripheral interrupts, or for reading the
enabled state of those interrupts. The remaining interrupts are enabled via the ISER1
register (Section 6.5.2
). Disabling interrupts is done through the ICER0 and ICER1
registers (Section 6.5.3
and Section 6.5.4).
