hi all,
I am trying to detect the CS (active low) after configuring it as below.
j1[7].function(pinj1_7_gpio);
j1[5].function(pinj1_5_cs1);
sim.cs[1].csar=0x0210;
sim.cs[1].csmr=0x021f; //(address range doesnt matter for my application)
sim.cs[1].cscr=0x0180; //auto acknowledge enable
please, note that there anre no more interface such as control signals and lower address lines.(A0 - A15) . i just want to check whether cs1 is getting low or not?
but i have tried all the way and i could not make it low(asserted) , so does any one have idea about this.
kindly reply urgently. thanks in advance.
