The limits for 2T are calculated as follows:
Lower limit of 2T: Lim_min_2T = (Lim_min + Lim_max) - (Lim_max - Lim_min)/2
Upper limit of 2T: Lim_max_2T = (Lim_min + Lim_max) + (Lim_max - Lim_min)/2
Note:
The data clock is available after the data clock control logic has detected the distance 2T (Start
bit), and then issues pulses with a delay of t
If the data clock control logic detects a timing or logical error (Manchester code violation), as
illustrated in
receiver remains in receiving mode and starts with the bit check. If the bit check was successful
and the start bit has been detected, the data clock control logic starts again with the generation
of the data clock (see
It is recommended to use the function of the data clock only in conjunction with the bit check 3, 6
or 9. If the bit check is set to 0 or the receiver is set to receiving mode via the pin POLLING/_ON,
the data clock is available if the data clock control logic has detected the distance 2T (Start bit).
Note that for Bi-phase-coded signals, the data clock is issued at the end of the bit.
If the result for “Lim_min_2T” or “Lim_max_2T” is not an integer value, it will be rounded up.
