6.14 Stop Mode Operation
In stop mode, all operations of the
μ
C cease, and the MFP pin is kept to high. 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). When the designated signal is accepted, the
μ
C awakens
and executes the next instruction. To prevent erroneous execution, the NOP instruction should follow
the STOP command. But In the dual-clock slow operation mode, the STOP instruction will also
disable the sub-oscillator oscillating; all operations of the
μ
C cease.
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
