The value shown represents the register’s initialized HEX value; X = n/a.
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 HVQFN32 package, and should not be written.
OUT2 pin is not supported in the HVQFN32 package, and this bit should not be written.
