PROVIDING ACKNOWLEDGEMENTS FOR SYSTEM POWER MANAGEMENT INTERFACE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17923110 Titled 'PROVIDING ACKNOWLEDGEMENTS FOR SYSTEM POWER MANAGEMENT INTERFACE'
Simplified Explanation
This abstract describes a system that allows a receiver to provide feedback in a serial bus communication. The method involves receiving a write command and data from the serial bus, writing the data to a specific register address, and using a second data frame to provide feedback about the received data. The feedback is provided by either driving the data line to indicate a transmission error or refraining from driving the data line to indicate a successful transmission. This allows for acknowledgement or negative acknowledgement of the received data.
Original Abstract Submitted
Systems, methods, and apparatus are configured to enable a receiver to provide feedback. In one example, a method performed at a device coupled to a serial bus includes receiving a write command from the serial bus in a datagram, writing a data byte received in a first data frame of the datagram to a register address identified by the datagram, and using a second data frame of the datagram to provide feedback regarding the datagram. Feedback may be provided by driving a data line of the serial bus to provide a negative acknowledgement during the second data frame when a transmission error is detected in the datagram, and refraining from driving the data line of the serial bus during the second data frame when no transmission error is detected in the datagram, thereby providing an acknowledgement of the datagram.
