Hardware event priority sensitive programmable transmit wait-window for virtual GPIO finite state machine

A device coupled to a communication link, comprising:

• a physical layer circuit that couples the device to the communication link;
• a finite state machine configured to detect occurrence of a first event corresponding to a change in general purpose input/output (GPIO) state, and occurrence of a second event corresponding to a different change in GPIO state, the second event occurring after the first event;
• and
• a timing circuit configured to initiate a wait period when the occurrence of the first event is detected,
• wherein the finite state machine is further configured to:
• constrain the physical layer circuit from transmitting virtual GPIO data corresponding to the first event during the wait period;
• cause the physical layer circuit to transmit the virtual GPIO data corresponding to the first event;
• and
• cause the physical layer circuit to transmit virtual GPIO data corresponding to the second event over the communication link after the wait period has expired when the second event occurs during the wait period.

A device coupled to a communication link, comprising:

• means for detecting occurrences of events, including occurrence of a first event corresponding to a change in general purpose input/output (GPIO) state, and occurrence of a second event corresponding to a different change in GPIO state, the second event occurring after the first event;
• means for providing a wait period configured to initiate the wait period when the occurrence of the first event is detected, wherein the second event occurs during the wait period;
• and
• means for transmitting data over the communication link,
• wherein the means for transmitting data is configured to refrain from transmitting virtual GPIO data corresponding to the first event during the wait period, and to transmit virtual GPIO data corresponding to the first event and the second event over the communication link after the wait period has expired.

A non-transitory storage medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:

• detect occurrence of a first event corresponding to a change in general purpose input/output (GPIO) state in a device coupled to a communication link;
• initiate a wait period when the occurrence of the first event is detected;
• refrain from transmitting virtual GPIO data corresponding to the first event during the wait period, wherein refraining from transmitting the virtual GPIO data includes foregoing an opportunity to transmit the virtual GPIO data during the wait period, and wherein the communication link is idle during at least a portion of the wait period;
• detect occurrence of a second event corresponding to a different change in GPIO state, the second event occurring during the wait period and after the first event;
• and
• transmit virtual GPIO data corresponding to the first event and the second event over the communication link after the wait period has expired.
