17.4 CPU Rewrite Mode
In CPU rewrite mode, the user ROM area can be rewritten by executing software commands from the
CPU. Therefore, the user ROM area can be rewritten directly while the microcomputer is mounted on-
board without having to use a ROM programmer, etc. Make sure the Program and the Block Erase
commands are executed only on each block in the user ROM area.
For interrupts requested during an erase operation in CPU rewrite mode, the R8C/10 flash module offers
an `erase-suspend` feature which allow the erase operation to be suspended, and access made avail-
able to the flash.
During CPU rewrite mode, the user ROM area be operated on in either Erase Write 0 (EW0) mode or
Erase Write 1 (EW1) mode. Table 17.3 lists the differences between Erase Write 0 (EW0) and Erase
Write 1 (EW1) modes.
