4.3 Read Instructions
Gen2 read instructions are performed through the CLI by using the target memory bank (or register) in the name of the
CLI command. It is inferred that commands that do not include the Gen2 memory bank name are accessing the USER
memory bank. In addition, read commands may specify single or multiple words, MaxArias registers, or use extended
EBV-formatted addressing.

Gen2 USER memory bank read command
data
Performs a standard Gen2 read command on the USER memory bank using a single 8-bit address
parameter (note: Gen2 read instructions of the other memory banks are performed with other CLI
commands described later in this section). The G2READ command has 2 parameters: address (addr)
and length (len). The address parameter defines the read instruction starting address and may not be
larger than x7F; the length parameter defines the number of words, with the first word being
addressed in the command’s address parameter – the length parameter can take on any value between
x0 and xFF.

instructions may be repeated without re-entering the parameters – entering the command on
its own will produce the same result. In addition, a subsequent read instruction may only
define the address – the previously defined length parameter will continue to be used.
respond with read data starting at the address defined in the read instruction, and continue to
the end of the memory bank.
