Execute the software commands
Execute the read array command
other than the flash memory
Start
End
Set the CPU clock frequency to 10 MHz or lower
in CPU rewrite mode
Internal memory wait state inserted
User ROM area accessed
CPU rewrite mode enabled
- To set the FMR01 bit to 1, write a 1 to the FMR01 bit
- Set it while "H" is applied to the NMI pin.
CPU rewrite mode disabled
-
To change the FMR01 bit from 1 to 0, enter read array mode
immediately after writing a 0.
Write the value to the FMR0 register in 8-bit units.
Do not generate an interrupt or a DMA or DMACII transfer
between these two settings.
and then write to address 0057h in 16-bit units.
Set the eight high-order bits to 00h.
