Address: 000C3H/010C3H
Address: 000C2H/010C2H
Cautions 1. Be sure to set bits 7 to 3 to “1”.
Note Be sure to set FFH to 000C2H, as these addresses are reserved areas. Also set FFH to 010C2H when the boot
The format of on-chip debug option byte is shown below.
Note Set the same value as 000C3H to 010C3H when the boot swap operation is used because 000C3H is replaced
Caution Bits 7 and 0 (OCDENSET and OCDERSD) can only be specified a value.
Remark The value on bits 3 to 1 will be written over when the on-chip debug function is in use and thus it will become

Be sure to set 000010B to bits 6 to 1.

software (bit 7 (LVION) of the low-voltage detection register (LVIM) is set to 0), it operates as
follows:
• Does not perform low-voltage detection during LVION = 0.
• If a reset is generated while LVION = 0, the LVION bit will be re-set to 1 when the CPU starts

however, when a reset occurs due to WDT and illegal instruction execution.
This is due to the fact that while the pulse width detected by LVI must be 200
