Section 22 Power-Down Modes
22.4
Usage Notes
When writing data to registers related to power-down modes, note the following suggestion.
In a case where the CPU writes data to the registers related to power-down modes, if the CPU
once starts executing the write instruction, the CPU keeps on executing the succeeding
instructions without waiting for the completion of writing data to the registers. If reflecting a
change of writing data to registers becomes necessary while the CPU is performing the succeeding
instructions, execute a dummy read for the same register between the write instruction to the
register and the succeeding instructions.
