LCD driver output
Low voltage reset/detector functions for
HT49R30A-1/HT49C30-1
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 op-
tions. Once the options of LVD is enabled, the user can
use the RTCC.3 to enable/disable (1/0) the LVD circuit
and read the LVD detector status (0/1) from RTCC.5;
otherwise, the LVD function is disabled.
The LVR has the same effect or function with the exter-
nal RES signal which performs chip reset. During HALT
state, LVR is disabled.
The definitions of RTCC register are listed in the follow-
ing table.
