WR0
WR[1:0] controls the read/write operation of the host interface.
In parallel mode, WR[1:0] meaning depends on whether the interface is in the 6800mode or the 8080 mode. In serial interface modes, these two pins are not used,connect them to VSS.

BM0
Bus mode: The interface bus mode is determined by BM[1:0]:
8080 (8-bit) Mode: BM1=1; BM0=0
6800 (8-bit) Mode: BM1=1; BM0=1
4-Wire SPI Mode: BM1=0; BM0=1
2-Wire I2C Mode: BM1=0; BM0=0

VLCDIN
High voltage LCD Power Supply.
Capacitor CL should be connected between VLCDOUT and VSS. When CL is used,
keep the trace resistance under 70W.
When using internal pump, connect VLCDIN and VLCDOUT together.
When using external pump, connect VLCDIN to external power and connect a
capacitor between VLCDOUT and Vss.

VB0-
LCD Bias Voltages. These are the voltage sources to provide SEG driving currents.
These voltages are generated internally. Connect capacitors of CBX of values
