Slave master-write/read datagram payload extension
First Claim
1. A method performed at a transmitting device for sending a datagram to a receiving device, comprising:
- generating an address field in the datagram;
setting a value of at least one bit in the address field to indicate a number of bytes of data associated with a data frame of the datagram, wherein the setting the value of the at least one bit in the address field includes;
detecting the number of bytes of data associated with the data frame,detecting whether a load-exponent mode is enabled or disabled, andsetting at least a first bit value and a second bit value in the address field according to the detected number of bytes of data and whether the load-exponent mode is enabled or disabled;
generating the data frame in the datagram, the data frame including the number of bytes of data; and
sending the datagram to the receiving device via a bus interface.

Abstract
Systems, methods, and apparatus for communicating datagrams over a serial communication link are provided. A transmitting device generates an address field in a datagram, sets a value of at least one bit in the address field to indicate a number of bytes of data associated with a data frame of the datagram, generates the data frame in the datagram, the data frame including the number of bytes of data, and sends the datagram to a receiving device. A receiving device receives a datagram from a transmitting device, decodes an address field of the datagram to detect a number of bytes of data included in a data frame of the datagram based on a value of at least one bit in the address field, and decodes the data frame to recover the detected number of bytes of data.

9. A transmitting device for sending a datagram to a receiving device, comprising:
-
a bus interface; and a processing circuit coupled to the bus interface and configured to; generate an address field in the datagram, set a value of at least one bit in the address field to indicate a number of bytes of data associated with a data frame of the datagram, wherein the processing circuit configured to set the value of the at least one bit in the address field is configured to; detect the number of bytes of data associated with the datagram, detect whether a load-exponent mode is enabled or disabled, and set at least a first bit value and a second bit value in the address field according to the detected number of bytes of data and whether the load-exponent mode is enabled or disabled, generate the data frame in the datagram, the data frame including the number of bytes of data, and send the datagram to the receiving device via the bus interface. - View Dependent Claims (10, 11, 12, 13, 14, 15)
