Specifically, what will a 24MHz clock signal look like on any GPIO port pin?
What factors will affect the shape of that signal?
- What is the rise time of any individual pin?
- What factors effect rise time?
- What is the fall time of any individual pin and what effects fall time?
- If VDDO is set at 1.8V, can a GPIO Port pin be connected directly or indirectly to a 3.3V pullup?
If there is a Technical Reference Manual available for any of the CYW20xxx products, that may contain the answers I seek.
Aside: I did find GPIO Documentation linked from Device Configurator in ModusToolbox @ https://infineon.github.io/btsdk-docs/BT-SDK/20721-B2_Bluetooth/API/group___g_p_i_o_driver.html . I don't see actual expected physical performance characteristics here.
