LCD Panel Interface
The HD66727 can change the shift direction of common drivers COM1–COM32 and COMS1 and COMS2
and segment drivers SEG1–SEG60 with the CMS and SGS bits. These bits can be selected according to the
mounting method such as the chip arrangement or wire leading. However, the output position of
annunciator drivers ASEG1–ASEG12 cannot be changed, so adjust it by software.
