THR.TXSYNH selects the sync type to be included.
following the preamble. If MR.ONEBIT is one, a Manchester encoded zero is transmitted to indi-
cate that a new character is about to be sent. If MR.ONEBIT is zero, a synchronization pattern is
sent for the duration of three bit periods to inaugurate the new character. The sync pattern wave-
form by itself is an invalid Manchester encoding, since the transition only occurs at the middle of
the second bit period.
The Manchester Synchronization Mode bit (MR.MODSYNC) selects sync pattern, and this also
defines if the character is data (MODSYNC=0) with a zero to one transition, or a command
(MODSYNC=1) with a one to zero transition. When direct memory access is used, the sync pat-
tern can be updated on-the-fly with a modified character located in memory. To enable this
mode the Variable Synchronization of Command/Data Sync Start Frame Delimiter bit
(MR.VAR_SYNC) has to be written to one. In this case, MODSYNC is bypassed and
