6.14.1 Stop Mode Wake-up Enable Flag for RC Port (SEF)
The stop mode wake-up flag for port RC is organized as an 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:

SEF
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

6.15 Hold Mode Operation
In hold mode, all operations of the
μ
C cease, except for the operation of the oscillator, Timer, Divider,
LCD driver, DTMF generator and MFP generator. The
μ
C enters hold mode when the HOLD instruction is
executed. The hold mode can be released in one of five ways: by the action of timer 0, timer 1, divider 0,
divider 1, the RC port. Before the device enters the hold mode, the HEF, PEF, and IEF flags must be set to
define the hold mode release conditions. For more details, refer to the instruction-set table and the
following flow chart.
