LCD Display Circuit (COM1 to COM17, SEG1 to SEG100, SSR and CSR)
The ML9042 has 17 common signal outputs and 100 segment signal outputs to display 20 characters (in the 1-line
display mode) or 40 characters (in the 2-line display mode).
The character pattern is converted into serial data and transferred in series through the shift register.
The transfer direction of serial data is determined by the SSR bit. The shift direction of common signals is
determined by the CSR bit. The following tables show the transfer and shift directions:

* Refer to the Expansion Instruction Codes section about the ABE bit, SSR bit, CSR bit, and AS bit.
Signals to be input to the SSR bit, CSR bit, ABE bit, and AS bit should be initially determined at power-on and be
kept unchanged.
