2. Restrictions on command usage to Endpoint when using Isochronous transfers
Compared to other transfers, Isochronous transfers have certain restrictions on handshake,
toggle, the number of transactions in a frame, etc., limiting the types of commands that can be
used. As a general rule, commands must not be issued to endpoints during Isochronous
transfers. While a request is being processed, the EP_Reset or EP_Invalid command may be
used as necessary.
(When using PVCI-I/F as the endpoint access method, use the EP_EOP command.)
