5.2.3
IER is an 8-bit readable/writable register that controls enabling and disabling of interrupt requests
IRQ5 to IRQ0.
IER is initialized to H'00 by a reset and in hardware standby mode.
They are not initialized in software standby mode.
Bits 7 and 6—Reserved: Only 0 should be written to these bits.
Bits 5 to 0—IRQ5 to IRQ0 Enable (IRQ7E to IRQ0E): These bits select whether IRQ5 to
IRQ0 are enabled or disabled.
