C
In CPU rewrite mode, the user ROM area can be rewritten when the CPU executes software commands.
Therefore, the user ROM area can be rewritten directly while the microcomputer is mounted on-board
without using a ROM programmer, etc. Verify the Program and the Block Erase commands are executed
only on blocks in the user ROM area.
For interrupts requested during an erasing operation in CPU rewrite mode, the M16C/26A Group flash
module offers an erase-suspend function which the erasing operation to be suspended, and access made
available to the flash. Erase-write 0 (EW0) mode and erase-write 1 (EW1) mode are provided as CPU
rewrite mode. Table 17.4.1 shows the differences between erase-write 0 (EW0) and erase-write 1 (EW1)
modes. 1 wait is required for the CPU erase-write control.
