IDT82V2108
T1 / J1 THDLC #1, #2 Upper Transmit Threshold (035H, 0B5H, 135H, 1B5H, 235H, 2B5H, 335H, 3B5H)
J1-00DH).
UTHR[6:0]:
The transmission will not stop until the last complete packet is transmitted and the THDLC FIFO fill level is below ‘UTHR[6:0] + 1’.
T1 / J1 THDLC #1, #2 Lower Interrupt Threshold (036H, 0B6H, 136H, 1B6H, 236H, 2B6H, 336H, 3B6H)
J1-00DH).
LINT[6:0]:
will be generated. It should be less than the value of the UTHR[6:0] unless both are equal to 00H.

Selection of the THDLC block (#1 or #2) whose registers are visible on the microprocessor interface is done via the THDLCSEL[1:0] (b5~4, T1/
These bits define the upper fill level of the FIFO. Once the fill level exceeds the UTHR[6:0] value, the data stored in the FIFO will start to transmit.
It should be greater than the value of the LINT[6:0] unless both are equal to 00H.
