(2) Low-voltage detection level select register (LVIS)
R01UH0106EJ0300 Rev.3.00
Oct 01, 2010
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.
Note
Caution 1. Be sure to clear bits 4 to 7 to “0”.
LVIS
The reset value changes depending on the reset source.
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.
