correspond with the data number specified by the device request. The CPU can
therefore process using INT_STATUSNAK interrupt. However, when class and
vendor request is used, wLength value corresponds to data transfer number in
data phase. With this setting, using this interrupt is not need. Data stage data
can be confirmed by accessing DATASIZE register.
