Note *3: The Special register set is accessible only when LCR bit-7 is set to a logic 1.
Note *4: Enhanced Feature Register, Xon 1,2 and Xoff 1,2 are accessible only when LCR is set to “BF“ Hex
Note *5: The value represents the register’s initialized HEX value. An “X” signifies a 4-bit un-initialize nibble.
