Hi all,
I am struggling to find the documentation that I need regarding the subject microcontroller. I have a fair amount of experience with other micros so it appears to me that this one is sorely lacking in documentation relative to what I have come to expect, and what there is doesn't seem to be well written. For example, in datasheet # KL26P64M48SF5 the term "POR" is used in one of the tables but is not defined anywhere. Now I know of course that "POR" is "Power On Reset", but if I didn't already have that knowledge where would I find it in the MKL data? There just seems to be a lot missing, including some things that I am looking for, specifically:
1> There must be a programming guide for the part somewhere that would include details related to where the processor starts after a POR event.
2> Page 7 (Table 6) of the datasheet references low voltage warning thresholds. This is extremely important to me because that term (and the datasheet itself) implies that there are eight different thresholds that the micro may be monitoring that may allow me to detect a falling battery voltage condition without having to install a separate supervisor chip. And assuming that there are indeed eight different programmable thresholds then how do I select the one (or ones) that I want?
So to sum it up, I would appreciate it if someone could point me in the direction of the documentation that I'm looking for, and if you might have the answers to my two questions I would appreciate that too!
Thank you in advance,
