Technique for RFFE and SPMI register-0 write datagram functional extension
First Claim
1. A method of sending a write command to a receiver via a bus interface, comprising:
- setting three or four consecutive bits in a configuration register to indicate an operation mode of the write command;
generating a command code field in the write command, wherein a most significant bit of the command code field has a value of 1 and remaining bits of the command code field are defined based on the operation mode;
including payload bytes in a payload field of the write command based on the operation mode; and
sending the write command to the receiver.

Abstract
Systems, methods, and apparatus for functionally extending a capability of a write datagram for RFFE and SPMI devices are provided. A sending device sets a configuration register to indicate an operation mode of a write command and generates a command code field in the write command. A most significant bit of the command code field has a value of 1 and remaining bits of the command code field are defined based on the operation mode. The sending device further includes payload bytes in a payload field of the write command based on the operation mode and sends the write command to a receiver via a bus interface. The sending device may also set a page-address register to include a page-address to be used if page segmented access (PSA) is enabled for the write command and set the configuration register to indicate whether the PSA for the write command is enabled.

11. A sending device for sending a write command to a receiver, comprising:
-
a bus interface; and a processing circuit configured to; set three or four consecutive bits in a configuration register to indicate an operation mode of the write command, generate a command code field in the write command, wherein a most significant bit of the command code field has a value of 1 and remaining bits of the command code field are defined based on the operation mode, include payload bytes in a payload field of the write command based on the operation mode, and send the write command to the receiver via the bus interface. - View Dependent Claims (12, 13)

14. A method of receiving a write command from a sender via a bus interface, comprising:
-
receiving a mode setting message for setting three or four consecutive bits in a configuration register to indicate an operation mode of the write command; receiving the write command from the sender; reading a command code field in the write command, wherein a most significant bit of the command code field has a value of 1 and remaining bits of the command code field are interpreted based on the operation mode; and detecting whether a payload field of the write command includes payload bytes to be processed based on the operation mode. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
