RESET:
This bit has no effect because the CPU16 always operates in supervisor mode.
The IARB field is used to arbitrate between simultaneous interrupt requests of the
same priority. Each module that can generate interrupt requests must be assigned a
unique, non-zero IARB field value.
Used for factory test only.
ICR fields determine internal and external interrupt priority, and provide the upper nib-
ble of the interrupt vector number supplied to the CPU when an interrupt is acknowl-
edged.
This field specifies which GPT interrupt source is given highest internal priority. Refer
