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.
