Low Voltage Reset/Detector Functions
There is a low voltage detector, LVD, and a low voltage reset circuit,LVR, implemented in the microcontroller. These
two functions can be enabled/disabled by configuration options. Once the LVD option is enabled, the user can use the
MODE.3 bit to enable/disable (1/0) the LVD circuit and read the LVD detector status (0/1) from bit MODE.5.
The MODE register definitions are listed below.
Rev. 1.00
0~1, 4, 6~7
