Use of PMOD

[K7MDL2]

Has anyone looked at using PMOD pins? Any test apps. I found the library function to set and get, but before I write something, checking to see if it already exists somewhere by someone. I did not see it in the supplied test apps or production utilities.

Same question as K7MDL2.
there is no a clear API doc, but in the code there are two functions: CaribouLite::GetPmodState () and void CaribouLite::SetPmodState (uint8_t val)
then how can I set Input or Output?
the HDL defines
PMOD
set_io io_pmod_out[0] B24
set_io io_pmod_out[1] A31
set_io io_pmod_out[2] B23
set_io io_pmod_out[3] B21
set_io io_pmod_in[0] A25
set_io io_pmod_in[1] A26
set_io io_pmod_in[2] A27
set_io io_pmod_in[3] B20
and
ioc_pmod_dir = 5'b00011, // PMOD connector bits IO pin direction
so it is confusing, could you clarify which PMODs are Input which ones are Output, are they I/O configurable? or fixed?
Thank you
Regards
