STV9936P/S

Format C is appropriate for updating large amounts of data from a full window or full screen. The

window, row and column addresses are incremented automatically when this format is applied.

Data is written to fill all the allocation memory of the windows.

The transmission formats are as follows:

1. Format A: S-FWR-FAC-D

→ FWR-FAC-D → FWR-FAC-D → FWR-FAC-D...Stop

2. Format B: S-FWR-FAC-D

→ FAC-D → FAC-D → FAC-D...Stop

3. Format C: S-FWR-FAC-D

→ D → D →D...Stop

Where:

S = Slave address = BAh

FWR = Format, Window and Row address

FAC = Format, Attribute and Column address

D = Control data, Color codes (3 bits) or Character codes (8 bits).

In Format C, the order of automatic incrementation for data D is first the column value, then the row

value, and then the window value.

2.1.3

Format, Window and Row Address (FWR)

Bit 7 indicates the ‘Window & Row’ byte when set to 1.

W[2:0]: Window Number

000: Control Data and Color boxes

001: Window 1

010: Window 2

011: Window 3

100: Window 4

R[3:0]: Row Number from 0 to 15. Each window has a maximum number of 16 rows.

2.1.4

Format, Attribute and Column Address (FAC)

Bit 7 indicates the ‘Attribute & Column’ byte when set to 0.

F: Format

0: Format A or B

1: Format C

A: Transmission of character code or color code

0: Character Code
