When starting up in boot mode, input pins may not be placed in high-impedance states until the internal supply
voltage stabilizes. Use the following procedure to power up in boot mode.
Write command codes and data to even addresses in the user ROM area.
If an erase operation in progress is aborted due to such as the NMI interrupt, hardware reset, or supply voltage
drop, the lock bit of the block which has been erased may become 0 (locked). To erase the same block again, set
the FMR02 bit in the FMR0 register to 1 (lock bit disabled) and then execute the block erase command.
To enter wait mode, set the FMR01 bit in the FMR0 register to 0 (CPU rewrite mode disabled) and then execute
the WAIT instruction.
To enter stop mode, use the following procedure:
When the CM05 bit in the CM0 register is set to 1 (main clock stopped), do not execute the following
commands:
(1) Input an “L” signal to the RESET pin and CNVSS pin
(2) Wait for td(P-R) (internal power supply stabilization time) or more after the voltage applied to the
(3) Input an “L” (pull-down) to the P6_5 or an “H” (pull-up) to the P6_7
(4) Input an “L” (pull-down) to the EPM (P5_5) and an “H” (pull-up) to the CE (P5_0)
(5) Input an “H” to the CNVSS pin
(6) Input an “H” to the RESET pin (out of reset)

Set the FMR01 bit to 0 (CPU rewrite mode disabled) before setting the CM10 bit to 1 (stop mode).
Execute the JMP.B instruction right after the instruction to set the CM10 bit to 1 (stop mode).
