Comments • Address may be specified in decimal, hex (# H), octal (# Q), or binary
(# B) formats.
• UPLoad is done by word (16 bit) access so address and byte_count must
be even.
• Data is returned in the Definite Block Response Data format:
# < non-zero digit> < digit(s)> < data byte(s)>
Where the value of < non-zero digit> equals the number of < digit(s)> .
The value of < digit(s)> taken as a decimal integer indicates the number
of < data byte(s)> to expect in the block.
• This command can also be used to retrieve data from a device with
registers in A16 address space. See DIAG:UPload:SADDress?
