Section 5 Interrupt Controller
5.2.3
IER is an 8-bit readable/writable register that controls enabling and disabling of interrupt requests
IRQ7 to IRQ0.
IER is initialized to H'00 by a reset and in hardware standby mode.
Bits 7 to 0—IRQ7 to IRQ0 Enable (IRQ7E to IRQ0E): These bits select whether IRQ7 to
IRQ0 are enabled or disabled.
