22.2 Configuration of Low-Voltage Detector
22.3 Registers Controlling Low-Voltage Detector
(1) Low-voltage detection register (LVIM)

V
DD
The block diagram of the low-voltage detector is shown in Figure 22-1.
The low-voltage detector is controlled by the following registers.
This register sets low-voltage detection and the operation mode.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
The generation of a reset signal other than an LVI reset clears this register to 00H.
