GPIOs concern
Dear Sir,
I have some concerns regarding GPIO setting.
According to KL720 HW Design guide v0.2 document, we saw that "GPIO do not have internal pull-up or pull-down resistor and they need to pull-down to GND if unused"
But in the KL720 datasheet v1.2, we saw that "GPIO could program general-purpose I/O and pull type."
Thus, I have some questions about GPIO setting:
- Could we program/set internal pull-up or pull-down resistors for GPIO?
- All GPIOs have interrupt function, right?
- What is the configured/recommendation for unused GPIO pins?
