The value shown in represents the register’s initialized HEX value; X = not applicable.
This bit is only accessible when EFR[4] is set.
Accessible only when LCR[7] is logic 0.
Baud rate registers accessible only when LCR[7] is logic 1.
Enhanced Feature Register, Xon1/Xon2 and Xoff1/Xoff2 are accessible only when LCR is set to ‘BFh’.
