8.10.5 Line Start Signal, LST
There are 4 modes of operation for the LST pin programmable via the serial interface, (see fg_mode[20]):
The LST is tri-stated either when OEB is driven high or via the appropriate control bit in the serial interface, (see data_format
register[22]). Table 18below details the LST timing for the different video modes, (see Figure 33 for specification of t1 and t2).
8.10.6 Frame Start Signal, FST
There are 3 modes of operation for the FST pin programmable via the serial interface:
The FST output is tri-stated either when OEB is driven high or via the appropriate control bit in the serial interface, (see
data_format register[22]).
The configuration details for FST can be found in fg_mode register[20].
1. Disabled (Always Low- Default).
2. Free running - LST signal occurs once at the beginning of every line.
3. All lines except blanking lines are qualified by LST.
4. Only Black and Visible Lines are qualified by LST.
1. Disabled (Always Low- Default).
2. Frame start signal. The FST signal occurs once frame, is high for 356 pixel periods (712 system clock periods) and qualifies
3. Shutter/Electronic Flash Synchronisation Signal - FST rises a the start of the video data in the first black/blank line after the
