EN INT
is executed again. Therefore, to enable these interrupts, the instructions MOV IEF, #I or EN
INT must be executed again. Otherwise, these interrupts can be disable by executing DIS INT
instruction. The bit descriptions are as follows:
w

2
3
IEF
4
w

5

0

7
Note: W means write only.
IEF.0 = 1 Interrupt 0 is accepted by overflow from the Divider 0.
IEF.1 = 1 Interrupt 1 is accepted by underflow from the Timer 0.
IEF.2 = 1 Interrupt 2 is accepted by a signal change on port RC.
IEF.3 Reserved
IEF.4 = 1 Interrupt 0 is accepted by overflow from the Divider 1.
IEF.5 & IEF.6 are reserved.
IEF.7 = 1 Interrupt 7 is accepted by underflow from Timer 1.
Stop Mode Operation
In stop mode, all operations of the
μ
C cease (excluding the operation of sub-oscillator and divider 1
when the dual-clock operation mode is selected). The
μ
C enters stop mode when the STOP
instruction is executed and exits stop mode when an external trigger is activated (by a falling signal
on the RC port). When the designated signal is accepted, the
μ
C awakens and executes the next
instruction (if the corresponding bits of IEF and PEF have been set, It will enter the interrupt service
routine after stop mode released). To prevent erroneous execution, the NOP instruction should follow
the STOP command.
Stop Mode Wake-up Enable Flag for Port RC (SEF)
The stop mode wake-up flag for port RC is organized as a 4-bit binary register (SEF.0 to SEF.3).
Before port RC may be used to make the device exit the stop mode, the content of the SEF must be
set first. The SEF is controlled by the MOV SEF, #I instruction. The bit descriptions are as follows:
0
1
2
SEF
w
w
w
w
3
Note: W means write only.
SEF 0 = 1 Device will exit stop mode when falling edge signal is applied to pin RC.0.
SEF 1 = 1 Device will exit stop mode when falling edge signal is applied to pin RC.1.
SEF 2 = 1 Device will exit stop mode when falling edge signal is applied to pin RC.2.
SEF 3 = 1 Device will exit stop mode when falling edge signal is applied to pin RC.3.
Hold Mode Operation
In hold mode, all operations of the
μ
C cease, except for the operation of the oscillator, timer, divider
and LCD driver. The
μ
C enters hold mode when the HOLD instruction is executed. The hold mode
