LINT[6:0]
The LINT[6:0] bits define the TDPR FIFO fill level which causes an internal interrupt
(LFILLI) to be generated. Once the TDPR FIFO level decrements to empty or to a value less
than LINT[6:0], LFILLI and BLFILL register bits will be set to logic one. LFILLI will cause
an interrupt on INTB if LFILLE is set to logic one.
The value of LINT[6:0] must always be less than the value of UTHR[6:0] unless both values
are equal to 00H.
