Hello everyone,
According to Zynq TRM, the PUDC_B pin must not be left floating. I agree with that but I am understanding that it is for a design in which only the Zynq chip is used. Am I rigth?
In case of a custom carrier card for inserting a Microzed board, is there any problem to drive this specific pin in the microheader as an input signal? I have read that one must be careful but, in what way? I mean, all the commercial carriers have a specific circuit with a jumper to select the PUDC_B status, however, the Microzed already has its own circuit to pull this signal up or down, so what is the need to drive this signal on both boards instead of using this pin as an additional external signal as I have in mind?
Thank you
Víctor
