Write Scratchpad Command [0FH]

After issuing the write scratchpad command, the master 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 bus master has

stopped writing data.

Read Scratchpad Command [AAH]

This command is used to verify scratchpad data and target address. After issuing the read scratchpad

command, the master begins reading. The first 2 bytes will be the target address. The next byte will be the

ending offset/data status byte (E/S) followed by the scratchpad data beginning at the byte offset (T4: T0).

The master may read data until the end of the scratchpad after which the data read will be all logic 1’s.
