23.4 Power Control
•
• 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
• When entering wait mode, insert a JMP.B instruction before a WAIT instruction. Do not execute any
• When entering stop mode, describe as follows.
When exiting stop mode by hardware reset, set RESET pin to “L” until a main clock oscillation is stabilized.
mode.
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 roadstead
the instructions following WAIT, and depending on timing, some of these may execute before the
MCU enters wait mode.
Program example when entering wait mode
(1) To use the BSET instruction for entering stop mode:
(2) To use the MOV instruction for entering stop mode:
Program Example:
Write the BSET instruction (BSET bit, base:16) as described below.
When entering stop mode, DMA transfer must be disabled.
Write the MOV instruction (MOV.B #IMM8, abs16) as described below.
When entering stop mode, DMA transfer must be disabled.
Change the src value (marked as “#21”), depending on your usage condition.
