MK20DN512VLQ10: What is output mode of EZP_Q in EzPort mode?

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.

 

Best regards,

Takashima
