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

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
