LCD Driver Output (1/3 Duty, 1/2 Bias, R/C Type)
LCD Segments as Logical Output
The SEG0~SEG23 also can be optioned as logical out-
put, once an LCD segment is optioned as a logical out-
put, the content of bit0 of the related segment address in
LCD RAM will appear on the segment.
SEG0~SEG7 is together byte optioned as logical out-
put, SEG8~SEG15 are bit individually optioned as logi-
cal outputs.

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 op-
tions. Once the LVD options 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 both LVR and LVD are disabled.
The microcontroller provides low voltage reset circuit in
order to monitor the supply voltage of the device. If the
supply voltage of the device is within the range
0.9V~V
LVR
, such as changing a battery, the LVR will au-
tomatically reset the device internally.
