3.4.3 Interrupt Option Register (IOR)
The Interrupt Option Register (IOR) is used to en-
able/disable the individual interrupt sources and to
select the operating mode of the external interrupt
inputs. This register is write-only and cannot be
accessed by single-bit operations.
Address: 0C8h
—
Write Only
Reset status: 00h
Bit 7, Bits 3-0 = Unused
Bit 6 =
LES
: Level/Edge Selection bit
When this bit is set to one, the interrupt source #1
is level sensitive. When cleared to zero the edge
sensitive mode for interrupt request is selected.
Bit 5 =
ESB
: Edge Selection bit
The bit ESB selects the polarity of the interrupt
source #2.
Bit 4 =
GEN
: Global Enable Interrupt When this
bit is set to one, all interrupts are enabled. When
this bit is cleared to zero all the interrupts (exclud-
ing NMI) are disabled.
When the GEN bit is low, the NMI interrupt is ac-
tive but cannot cause a wake up from STOP/WAIT
modes.
This register is cleared on reset.

terrupt request.
