The data transmission is permitted to change from format (a) to format (b) and (c), or from format (b) to format
(a), but not from format (c) back to format (a) and (b). The alternation between transmission formats is config-
ured as the state diagram shown in Figure 3 on page 5.

3.2 Address bus administrator
The administrator manages bus address arbitration of internal registers or user fonts RAM during external
data write in. The external data write through serial data interface to registers must be synchronized by inter-
nal display timing. In addition, the administrator also provides automatic increment to address bus when exter-
nal write using format (c).
3.3 Vertical display control
The vertical display control can generates different vertical display sizes for most display standards in current
monitors. The vertical display size is calculated with the information of double character height bit(CHS), verti-
