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.
