Bits 7 ~ 4:

Not used, set to “0” at all time

Bit 3 (LVDEN): Low Voltage Detect Enable Bit

0 : LVD disable

1 : LVD enable

Bit 2 (/LVD): Low Voltage Detector. This is a read only bit. When the VDD pin

voltage is lower than LVD voltage interrupt level (selected by LVD1 and

LVD0), this bit will be cleared.

0 : low voltage is detected

1 : low voltage is not detected or LVD function is disabled

Bit 1~Bit 0 (LVD1~LVD0): Low Voltage Detect level select bits
