Notes 1. M2, M1, M0 is code specified by SMM command.

2. Some other chip handles R0 to R7 outputs.

3. Some other chip handles R8 to R15 outputs.

M2, M1, M0 = 111 is for single chip configuration. In this case, R15/C42 to

R8/C49 are used as row signal outputs, and all 16 row signals are output

from this chip.

These drivers perform switching of the analog level in correspondence to the contents of the display data read out

from the data memory and the timing signals supplied from the LCD timing control circuit, according to the select level,

non-select level, and phase supplied from the LCD voltage control circuit, and generates and outputs row and column

driver signals in order to directly drive the LCD.
