• Virtual flash emulation function
The microcomputer has the function to map 8-Kbyte memory blocks of the internal RAM (maximum for 32185
is 4 blocks, for 32186 is 8 blocks) into areas (L banks) of the internal flash memory that are divided in 8-Kbyte
units. This functions is referred to as the Virtual Flash Emulation Function.
This is the function allows shift from the contents of internal flash memory at the addresses specified by the
Virtual Flash L Bank Register to the data located in 8-Kbyte blocks of the internal RAM. That way, the relevant
RAM data can read out by reading the content of internal flash memory.
• Dummy access areas
Address H'0080 0600 to H'0080 0603 are dummy areas.
When there is access to these areas, writing value is disabled and reading value is undefinited.
In addition, it does not effect on the other SFR area by writing and reading out operation to dummy access area.
