Systems, methods, and apparatus improve accuracy of trigger timing by compensating for clock pulses that are suppressed when datagrams are transmitted over a serial bus. A method includes configuring an initial value of an output of a counter in a timing circuit, enabling the counter to count pulses in a clock signal received from the serial bus, determining that a datagram is being transmitted on the serial bus while the counter is counting the pulses in the clock signal, providing a timing value that represents a current value of the output of the counter adjusted to compensate for one or more clock pulses suppressed during transmission of the datagram, and providing a trigger when the timing value reaches a maximum value or a minimum value. The counter may be a countdown counter and two clock pulses may be suppressed for each sequence start condition transmitted on the serial bus.
