INTSRB = 0 Internal shunt resistor is available between V2~V6
= 1 External shunt resistor is needed between V2 ~V6.
PMPV3B = 0 Triple pump voltage available (suggeset while VDD=3v)
= 1 Double pump voltage available (suggest while VDD=4.5v)
BIAS7B = 0 1/7 bias available ( suggeset for 32 common)
= 1 1/5 bias available (suggest for 16 common)
COM32B =0 1/32 duty, COM0~COM31 output available
=1 1/16 duty, COM0~ COM15 output available
All bit can write only.
At initial reset, LCDM1 is 0000B
LCD frame rate divider (LDIV with SR=12H)
The LDIV register is used to define the frame rate of LCD driver. The relationship between the frame rate of LCD driver
and the LDIV value is : FLCD = 32768 / [(LDIV+1)*64] . If LDIV value is set to 7 (default value), the frame rate of LCD
driver is 64Hz. For 1/16 duty ( while LCDM1 bit 3=0), please MOV LDIV, #1111B to get 64 hz frame rate. Otherwise the
fame rate will be 128HZ.
