Currently we are building a flash programming equipements using EzPort for the MK20DN512VLQ10.
If we add external 10k ohm pull down resistor to the EZP_Q pin of the MK20DN512VLQ10, EZP_Q cannot output high level.
If we add external 10k ohm pull up resistor or no external resistor to EZP_Q pin, EZP_Q can output high level.
Why does this phenomenon occur?
What is output mode of EZP_Q in EzPort mode?
Please reply as soon as possible.
