I'm an embedded systems designer and I'm new to the Kinetis platform. I'm part of a team of developers designing a custom PCB based around the KL46Z. I have the reference schematics for the FRDM-KL46Z board and the PDF documentation available from the http://freescale.com/frdm-kl46z website. However, I haven't been able to find in depth descriptions of the pin layout or further application notes besides the precompiled examples.
Where may I find this sort of documentation?
Some of the specific questions I have include:
-Which GPIO are edge sensitive vs level sensitive?
-How to assign additional GPIO as chip select signals to address multiple SPI slaves? (Using the same SPI port, for example port zero).
The KL46P121M48SF4 pdf only describes the pin layout and names each pin's basic function. I have been searching around this forum but I haven't been able to find previous posts with my questions.
Thanks in advance! Any help would be appreciated.
