(2) Low-voltage detection level select register (LVIS)
210
Address: FF51H, After reset: 00H
Symbol
LVIS
This register selects the low-voltage detection level.
This register can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H
Note For a reset by LVI, the value of LVIS is not initialized.

Bits 4 to 7 must be set to 0.
If a value other than the above is written during LVI operation, the value becomes
undefined at the very moment it is written, and thus be sure to stop LVI (bit
7(LVION) = 0 on the LVIM register) before writing.
