CHAPTER 6 LOW POWER CONSUMPTION MODE
■ Access to the Low Power Consumption Mode Control Register
Switching to low power consumption mode (including stop mode and sleep mode) is performed by writing
to the low power consumption mode control register. Only the instructions listed in Table 6.3-2 should be
used for this purpose. If other instructions are used for switching to low power consumption mode,
operation cannot be assured. To control functions not listed in Table 6.3-2, any instruction can be used.
When word-length is used for writing to the low power consumption mode control register, even addresses
must be used. Writing with odd addresses to switch to low power consumption mode may cause a
malfunction.
