Timed-trigger synchronization enhancement

A data communication apparatus comprising:

• an interface circuit configured to couple the data communication apparatus to a serial bus and configured to receive a clock signal from the serial bus;
• a plurality of counters configured to count pulses in the clock signal;
• and
• a controller configured to:
• receive a datagram from the serial bus, the datagram including a plurality of data bytes corresponding to the plurality of counters;
• configure each counter in the plurality of counters with a count value based on content of a corresponding data byte in the datagram, wherein each counter is loaded with its respective count value after a valid parity bit for the corresponding data byte is received from the serial bus;
• cause each counter in the plurality of counters to refrain from counting until all counters in the plurality of counters have been loaded with their respective count values;
• and
• actuate a trigger when a counter associated with the trigger has counted to zero.

A non-transitory processor-readable storage medium having one or more instructions which, when executed by at least one processor of a processing circuit in a receiver, cause the at least one processor to:

• receive a datagram from a serial bus, the datagram including a plurality of data bytes corresponding to a plurality of counters;
• configure each counter in the plurality of counters with a count value based on content of a corresponding data byte in the datagram, wherein each counter is loaded with its respective count value after a valid parity bit for the corresponding data byte is received from the serial bus;
• cause each counter in the plurality of counters to refrain from counting until all counters in the plurality of counters have been loaded with their respective count values;
• and
• actuate a trigger when a counter associated with the trigger has counted to zero.

A data communication apparatus comprising:

• means for receiving a datagram from a serial bus, the datagram including a plurality of data bytes corresponding to a plurality of counters;
• means for controlling the plurality of counters, each counter in the plurality of counters being configured with a count value based on content of a corresponding data byte in the datagram, wherein the each counter is loaded with its respective count value after a valid parity bit for the corresponding data byte is received from the serial bus, and wherein the means for controlling the plurality of counters is configured to cause each counter in the plurality of counters to refrain from counting until all counters in the plurality of counters have been loaded with their respective count values;
• and
• means for actuating a trigger when a counter associated with the trigger has counted to zero.
