RE: Asynch Serial Port 1 FIFO
That comment is true for ETRAX 100 only. ETRAX 100LX and
the MCM has a 64 byte FIFO for serial port 1 (i.e. the
same FIFO size as for all other interfaces). I have tested
to run the serial ports with the maximum speed allowed by
Etrax (6.25 MBit/s) without dropping characters. Note that
you have to connect your device before the serial transceiver
to run at speeds higher than 115200bps.

Subject: Asynch Serial Port 1 FIFO
The design reference and the E100LX board schematics point to the fact
that asynchronous serial port 1 (ser1) does not have a FIFO buffer.
Does the same apply to the MCM version of the E100LX? If so, has anyone
used ser1 (without a FIFO) in the MCM or E100LX ? What were the maximum
baud rates achieved, without data loss?
Thx for your help,
