q Internal RAM area
At hardware reset ................................................................................. Retains the state immediately before reset (Note 22).
At software reset.................................................................................................... Retains the state immediately before reset.
At termination of the stop or wait mode
(when hardware reset is used for the termination.)....................................Retains the state immediately before the STP or
WIT instruction is executed.
At power-on reset..................................................................................................................................................... Undefined.
Notes 22 : When a reset operation starts while writing to the internal RAM area is in process, the microcomputer will be
reset before the completion of writing. Accordingly, the contents of the area where the writing was in process
will become undefined.
