1. When exiting stop mode by hardware reset, the device will startup using the on-chip oscillator.
2. Set the MR0 bit in the TAiMR register(i=0 to 4) to “0”(pulse is not output) to use the timer A to exit stop
3. When entering wait mode, insert a JMP.B instruction before a WAIT instruction. Do not excute any

instructions which can generate a write to RAM between the JMP.B and WAIT instructions. Disable the
DMA transfers, if a DMA transfer may occur between the JMP.B and WAIT instructions. After the WAIT
instruction, insert at least 4 NOP instructions. When entering wait mode, the instruction queue reads
ahead the instructions following WAIT, and depending on timing, some of these may execute before the
microcomputer enters wait mode.
sets the CM10 bit in the CM1 register to “1”, and then insert at least 4 NOP instructions. When entering
stop mode, the instruction queue reads ahead the instructions following the instruction which sets the
CM10 bit to “1” (all clock stops), and, some of these may execute before the microcomputer enters stop
mode or before the interrupt routine for returning from stop mode.
