Yes, you can use a 100nF ceramic disc (0.1uF)
They are non-polarized, meaning it can go either way around.My 1st CPLD project using the Xilinx XC9536Title says it all - for those of you who are considering the use of a CPLD or FPGA (programmable logic) in your electronics ventures, I've documented…
