The period (Tp) has a duration of 1ms and is formed as follows:
400μs
in which the
RDP
(data) and
RCP
(clock) lines are high
300μs
in which the
RDP
is low if the bit is equal to 1 (
RCP
is always high)
300μs
(Tck) in which the
RCP
is low (
RDP
maintains the level it had before)
At the end of the period
RCP
and
RDP
are once again high

The serial protocol sends an

standard protocol packet to the

output (baudrate =
