Accessing the setup command buffer
Setup Packets are sent from the host to a device’s Endpoint0 and consist of 8 bytes of
command data. When the SIE receives a Setup packet from the host, it stores the 8 bytes of
data in the Command Buffer. The command buffer is accessed via the indexed USB Setup
Command Value register (USCV). The USB Setup Command Index register (USCI) is used
to select the byte from the command buffer that is read when accessing the USCV register.
USB registers
The USB module is controlled via registers mapped into the SFR space. The USB SFRs
consist of the following:
