Descriptions
IN_TRF_CNT
In-transfer data count.
There is no mode selection for the control endpoint (but it
operates like manual mode).The local-CPU has to fill the control-
endpoint buffer with the data to be sent for an in-token and to
write the count of bytes in this register. When zero is written into
this field, a zero length packet is sent to the host. When the count
written in the register is more than the MPS, the data sent will be
of only MPS.
