The value shown represents the register’s initialized HEX value; X = not applicable.
These registers are accessible only when LCR[7] = 0.
These bits are only accessible when EFR[4] is set.
This function is not supported in the HVQFN48 package; TXRDY and RXRDY are removed.
The Special Register set is accessible only when LCR[7] is set to a logic 1.
Enhanced Feature Register, Xon1/Xon2 and Xoff1/Xoff2 are accessible only when LCR is set to ‘BFh’.
