16.6 On-board Write Mode
In on-board write mode, flash memory is overwritten by manipulating the control registers through software.
Table 16-6-1 lists the control registers to be used in on-board write mode.
Table 16-6-1 Flash Memory Register List
*1: FLMODR[3:0] uses the values of MMOD1 and 0 and EXMOD1 and 0, and FLMODR[7:4] is x'0.
If an on-board write is performed, some bus control signal pins (except for RE, WE1, and WE0) and the address
and data signal pins operate.
The pins that operate are listed below:
The RE, WE1, and WE0 signal pins each output a high signal.
If the pins are set for other signals by the I/O port register settings, they operate in accordance with the register
settings.
Design the board of any external device that is to be connected to above signal pins in such a way that no difficulty
will be encountered even if the above signal pins do operate.
