Command 5
Table 20
Command 5 format
Command 5 is used to load character data into the DCR
Character Register. The data will specify either a
Character Font Code, the Test Code, the Carriage Return
Code or the Space Code. These codes are explained in
detail in Section 8.1.
9.7
Command 6
Table 21
Command 6 format
Command 6 loads the programmable 6-bit counter of the
OSD clock oscillator. The output frequency (f
OSD
) is a
function of the decimal value of the 6-bits loaded in by
Command 6; see Chapter 11.

Command 7
Table 22
Command 7 format
This command loads Control Register 1 with data that
selects the scanning mode, the output polarity of signals
FB, ACM, R, G, B and I, and also enables/disables the
OSD clock.
With reference to the scanning modes: 1V/2V is the
conventional NTSC or PAL scanning mode; 1V/2H is the
Line Progress Scan used for the IDTV in NTSC and 2V/2H
is for the PAL system and is known as 50 to 100 Hz scan
conversion.
