The ETRAX network driver is responsible for flashing LED's when
packets arrive and are sent. It uses macros defined in

what YOU choose in this option. The actual bits used are configured
separately. Select this if the LEDs are on port PA. Some products
put the leds on PB or a memory-mapped latch (CSP0) instead.

Configures the direction of general port A bits. 1 is out, 0 is in.
This is often totally different depending on the product used.
There are some guidelines though - if you know that only LED's are
connected to port PA, then they are usually connected to bits 2-4
and you can therefore use 1c. On other boards which don't have the
LED's at the general ports, these bits are used for all kinds of
stuff. If you don't know what to use, it is always safe to put all
as inputs, although floating inputs isn't good.

This is often totally different depending on the product used. Bits
0 and 1 on port PB are usually used for I2C communication, but the
kernel I2C driver sets the appropriate directions itself so you
don't need to take that into consideration when setting this option.
If you don't know what to use, it is always safe to put all as
inputs.
