The XFR2VBUS supports 1 command in its command FIFO, 1 XOUT to define the address and size (4 Byte, 32 Byte, 64 Byte, aligned). This will cause the VBUSP read command to be issued. Only 1 read command can be in flight. The read address defines the offset of the 64 Byte of read data. The read size defines the size of the transfer, 4 Byte, 32 Byte, 64 Byte, aligned Offset + size must be aligned to 32 Byte width of the bus. 1 XIN, the software can see the status of command FIFO and read data FIFO.
Note: XIN of the read data will fully pop the data, independent of XIN size.
