LVT4 [20H 23H]: V timing data readout
Function:
This command reads the V timing data of the program whose number has
been designated. When the program number is 0, it reads out the data from
the buffer RAM. When the program has any number from 1001 to 2000, the
command reads out from the fixed data. When the program number is 9999,
the command reads the data from the command work RAM.
