13.4.2 Sleep Mode Entry

Entry into the Sleep mode from any other mode does not require a clock switch. This is due to the fact that once in the Sleep mode, no clocks are needed.

Note: If software writes to the CRU SFRs before going into the Sleep mode, it is recommended a read be done of the SFRs to Flash the write before executing the WAIT instruction that initiates the Sleep mode.
