Note 1* The General Register sets are accessible only when CS is a logic 0. Set A is accessible when CHSEL
is a logic 1 and set is accessible when CHSEL is a logic 0.
Note 2* The Baud Rate register and AFR register sets are accessible only when CS is a logic 0 and LCR bit-7 is
a logic 1 for the register set (A/B) being accessed.
Note 3* The value between the square brackets represents the registers initialized HEX value, X = N/A.
