Figure 104 Advanced Device Mode Setup

Device structure and supported class requests are defined in the same
manner as Easy Device Emulation as described starting on page 131.

Note however that all of the endpoint behavior settings are grayed out
because the endpoint responses are programmed in the supported
commands page.

Define Command sets on the Supported Commands page. Each
Command Set includes a command stage, which has to be a setup or out
transaction to a non-zero endpoint. This data stage can have one or more in or
out transactions to any endpoint and may contain one last in or out transaction
as a status stage.

The 248 KB memory of the Advanced Device Emulation is divided into 31
command sets. Each command set occupies 8 KB that includes all the fields
of the packets, like PID, data payload and CRC. In cases where a Command
Set is larger than 8 KB, it occupies more than one set, so the total number of
Commands Sets is reduced. For instance, if one command uses 12 KB, 2
command sets are assigned to it, so the total commands number is reduced to
30 from 31.Defining a Command Set
