Write Bit
This command modifies the bits of the word specified by a logical
address. This address must point to a word within a file. Unlike the
unprotected and protected bit writes in the basic commands, this
command can change the bits in a single word only.
Unless otherwise stated, values shown are in hexadecimal, and each block
shown represents one byte.
Write File
Use this command to write data into a file at the destination. Use the
address (L ADDR) field to specify a logical file address. In the first
packet of a transaction, the packet-offset value is 00. In subsequent
packets of a transaction, use the packet-offset field to specify the word
(within the file) at which the write starts for the packet. Use the
total-transaction field to specify the number of bytes to write in the total
transaction.
