1.3.1 WRITE SCRATCHPAD Command
This command is used to write data to the scratchpad. The scratchpad is an additional page that acts as a buffer when writing to memory. After issuing the write SCRATCHPAD command, the host must first provide the 2-byte target address, followed by the data to be written to the scratchpad. The data will be written to the scratchpad, starting at the byte offset (T4:T0). The ending offset (E4:E0) will be the byte offset at which the host stops writing data; only full data bytes are accepted. If the last data byte is incomplete, its content will be ignored, and the partial byte flag, PF, will be set.
