Special Rx FIFO Data Unloading at locations 0x0200 and 0x0600
The XR17V352 also provides the same RX FIFO data along with the LSR status information of each byte side-
by-side, at locations 0x0200 (channel 0) and 0x0600 (channel 1). The Status and Data bytes must be read in
16 or 32 bits format to maintain data integrity. The following tables show this clearly.
