We are trying to use the TL16C554A quad uart
The transmission rate we are interested is quite low: 4800bps
We used the fifo polled mode as well as the fifo interrupt mode b programming the registers as described in the Datasheet.
1) In fifo polled mode we check the lsbit in the LSR
2) In Fifo interrupt mode we check the IIR bit 3 with a threshold set t
In both the use we lost a lot of data and we receive correctly 16-18 char only for each of the transmitted sentence.
Unfortunately no application note or reference design is available fro TI.
Is there anyone that have experience with problems with such a device??
thanks
