values above 1715 (FISE = 1) or 1727 (FISE = 0) are not allowed; increasing HTRIG decreases
delays of all internally generated timing signals; the default value is 0
increasing VTRIG decreases delays of all internally generated timing signals, measured in half lines;
variation range of VTRIG = 0 to 31 (1FH); the default value is 0

LSBs of the respective bytes are encoded immediately
after run-in and framing code, the MSBs of the respective
bytes have to carry the parity bit, in accordance with the
definition of line 21 encoding format.
