9.5.3.1
In stop mode, all clocks are stopped. Since the CPU clock and peripheral function clocks are stopped, the CPU
and the peripheral functions which are operated by these clocks stop their operation. The least power is required
to operate the MCU in stop mode. Enter stop mode from main clock mode.
Stop mode is entered by setting the CM10 bit in the CM1 register to 1 (all clocks stop) while the NMI pin is
held “H”. Also, bits MCD4 to MCD0 in the MCD register become 01000b (divide-by-8 mode) by setting the
CM10 bit to 1.
Figure 9.15 shows a procedure to enter stop mode.
When entering stop mode, the instructions following CM10 = 1 instruction are stored into the instruction queue,
and the program stops. When stop mode is exited, the instruction lined in the queue is executed before the exit
interrupt routine is handled.
Insert the jmp.b instruction as follows after the instruction to set the CM10 bit to 1.
