For IN token, the value of MXPLD is used to define the data length to be transmitted and indicate the data buffer is ready.
For OUT token, it means that the controller is ready to receive data from the host and the value of MXPLD is the maximal data length comes from host.
(2) When the register is read by CPU,
For IN token, the value of MXPLD is indicated by the data length be transmitted to host
For OUT token, the value of MXPLD is indicated the actual data length receiving from host.
