To enter stop mode, set the FMR01 bit in the FMR0 register to 0 (CPU rewrite mode disabled) and then the
CM10 bit in the CM1 register to 1 (stop mode). An instruction queue pre-reads 4 bytes from the instruction
which sets the CM10 bit to 1 (stop mode) and the program stops.
Insert at least four NOP instructions following the JMP.B instruction after the instruction which sets the CM10
bit to 1.
•
To enter wait mode by setting the CM30 bit to 1, set the FMR01 bit in the FMR0 register to 0 (CPU rewrite
mode disabled) before setting the CM30 bit to 1.
To enter wait mode with the WAIT instruction, set the FMR01 bit in the FMR0 register to 0 (CPU rewrite mode
disabled) and then execute the WAIT instruction. An instruction queue pre-reads 4 bytes from the WAIT
instruction and the program stops. Insert at least four NOP instructions after the WAIT instruction.
•
Program example to enter stop mode
BCLR 1, FMR0; CPU rewrite mode disabled
BSET 0, PRCR; Protect disabled
FSET I; Enable interrupt
BSET 0, CM1; Stop mode
