• When the isochronous transfer is set, Alternate can be used in the range of 0 and 1 for the same
• Endpoint information can be set up to 10 in maximum.
• Endpoint information of 10 pieces must be written.
• All information of endpoints which are not used must be written as 0.
A list of restrictions of settable transfer method, transfer direction, and maximum packet size is
described in table 36.4.
