Setting Procedure for EW1 Mode
Start
End
Set the CPU clock frequency to 10 MHz
or lower in CPU rewrite mode
Internal memory wait state inserted
CPU rewrite mode enabled
- To set the FMR01 bit to 1, write a 1 to the FMR01 bit
- Set it while the NMI pin level is held "H".
Enter EW1 mode
- To set the FMR11 bit to 1, write a 1 to the FMR11 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 setting.
immediately after writing a 0 to the bit while the FMR01 bit is set to 1.
Do not generate an interrupt or a DMA or DMACII transfer between
these two setting.
and then write to address 0057h in 16-bit units.
Set the eight high-order bits to 00h.
