PSoC 4 MCU

Hello,

Please tell me the behavior state of GPIO pin during POR  of PSoC4000S.

if the VDD passes over  "Power On Reset" voltage, the state of GPIO pin follows GPIO configuration.

if the VDD is under  "Power On Reset" voltage, how is the state of GPIO pin?

I think that it is "Analog input" and Hi-Z. Is this correct?

Best regards,

Yocchi

State: “High Impedance Analog”

Hello,

Thank you very much for your reply.

I could find "high-impedance analog mode" in "AN86439 - PSoC® 4 - Using GPIO Pins" too.
