Notes on the microprocessor mode and transition after shifting from the micropro-
cessor mode to the memory expansion mode / single-chip mode
In microprocessor mode, the SFR, internal RAM, and external memory space can be accessed.
For that reason, the internal ROM area cannot be accessed.
After the reset has been released and the operation of shifting from the microprocessor mode has started
(“H” applied to the CNVSS pin), the internal ROM area cannot be accessed even if the CPU shifts to the
memory expansion mode or single-chip mode.
Notes on CNVss pin reset at "H" level
When the CNVss pin is reset at "H" level, the contents of internal ROM cannot be read out.
