Commands
There are three basic types of commands: Initialization, Data and General
commands. Respectively, these are used to initialize the hub and the embedded
functions; for data flow between the hub, embedded functions and the host; for
controlling individual downstream ports; and general hub operation.
The embedded microcontroller has access to the hub functions via 3 dedicated
control registers (Command, Data, Status), which are mapped to the external data
memory address space of the 80C51. See
Section 10.4 “Hub control registers”
.
A summary of the available commands is given in
Table 20
. Some commands have
the same command code (e.g., Read Buffer and Write Buffer). In these cases, the
direction of the transaction (read or write) indicates which command is executed.
To execute a command, the specified code must be written to the Command register.
Any following transaction data can then be read or written via the Data register.
