25.2 Configuration of Low-Voltage Detector
25.3 Registers Controlling Low-Voltage Detector
(1) Low-voltage detection register (LVIM)
472
A block diagram of the low-voltage detector is shown below.
The low-voltage detector is controlled by the following registers.
• Low-voltage detection register (LVIM)
• Low-voltage detection level selection register (LVIS)
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.
