(2) Low-voltage detection level select register (LVIS)
634
Address: FFFAAH
Symbol
This register selects the low-voltage detection level.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation input sets this register to 0EH.
LVIS
Caution 1. Be sure to clear bits 4 to 7 to “0”.
Note The reset value changes depending on the reset source.

Figure 20-3. Format of Low-Voltage Detection Level Select Register (LVIS)
If the LVIS register is reset by LVI, it is not reset but holds the current value. The value of this
register is reset to “0EH” if a reset other than by LVI is effected.
After reset: 0EH
