LCD Driver Output
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 config-
uration options. Once the configuration options for the
LVD is enabled, bit RTCC.3 can be used to enable or
disable the LVD circuit. The LVD detector status can be
monitored via bit RTCC.5.
The LVR has the same effect or function as the external
RES signal which performs a chip reset. During the
Power Down mode the LVR is disabled.
