these patterns. If the start frame delimiter, also known as start bit, is one bit, (ONEBIT at 1), a
logic zero is Manchester encoded and indicates that a new character is being sent serially on the
line. If the start frame delimiter is a synchronization pattern also referred to as sync (ONEBIT at
0), a sequence of 3 bit times is sent serially on the line to indicate the start of a new character.
The sync waveform is in itself an invalid Manchester waveform as the transition occurs at the
middle of the second bit time. Two distinct sync patterns are used: the command sync and the
data sync. The command sync has a logic one level for one and a half bit times, then a transition
to logic zero for the second one and a half bit times. If the MODSYNC field in the MR register is
set to 1, the next character is a command. If it is set to 0, the next character is a data. When
direct memory access is used, the MODSYNC field can be immediately updated with a modified
character located in memory. To enable this mode, VAR_SYNC field in MR register must be set
to 1. In this case, the MODSYNC field in MR is bypassed and the sync configuration is held in
