[2] Set the interrupt priority levels of the interrupts not being used to exit stop mode
example:
• Before Execution of WAIT Instruction
[1] Set the interrupt priority level of the interrupt being used to exit stop mode
[3] Set the IPL in the FLG register. Then set the minimum interrupt priority level
[4] Set the I flag to "1"
[5] Set the CM10 bit in the CM1 register to "1" (all clocks stop) after setting the
Set the interrupt priority level required to exit stop mode to "7" immediately after
exiting stop mode.
[1] Exit stop mode using the /NMI interrupt
[2] Generate a dummy interrupt
[3] Set the CM10 bit to "1"
bits in the RLVL register, to "7".

use the following procedure to set the CM10 bit to "1".
Set each interrupt priority level after setting the minimum interrupt priority level
required to exit stop mode and wait mode, controlled by the RLVL2 to RLVL0
used to exit stop mode)
