1: Color Code
When reading or writing control data and/or color boxes, bit A must be set to 0. For Character
codes, A must be set to 1.
C[4:0]
: Column Number
There are 32 possible columns.
00000: 1 column
11111: 32 columns
2.1.5
Control Data, Color Codes or Character Codes (D)
Color codes are stored on 3 bits. Control data and Character codes are stored on 8 bits.
2.1.6
Configuration of Transmission Formats
All formats must start with the S, FWR and FAC bytes.
All FAC values referred to in this datasheet correspond to transmission formats A or B.
2.2
Format Changing
To change from Format A to Format B
S-FWR[0]- FAC[0]-D[0]
FWR[1]- FAC[1]- D[1]
FWR[2]- FAC[2]- D[2]
FAC[3]- D[3]
FAC[4]-
D[4]
FAC[5]- D[5]...
The F bit from the FAC byte is always 0 in this case.
To change from Format A to Format C
S - FWR[0]- FAC[0]- D[0]
FWR[1]- FAC[1]- D[1]
FWR[2]- FAC[2]- D[2]
D[3]
D[4]
D[5]...
The “F” bit from the FAC byte is as follows:
F[0] = F[1] = “0”
F[2] = “1”
To change from Format B to Format A
S - FWR[0]- FAC[0]-D[0]
FAC[1]- D[1]
FAC[2]-D[2]
FWR[3]- FAC[3]- D[3]
FWR[4]- FAC[4]-
D[4]...
