How do i find out the explanation or the definition to the abbreviations for the i/o pins on the kl02 32 pin mcu? For example some of the ones that are listed are PTB, PTA,IRQ, VREFH, and VREFL. Anything will help, thanks.
I don^t think that there is a general abbreviation list but if you search for tehe one that you are interested in in the user's manual there will be a description of it.
Basically all with PTx are GPIOs. PTA1 is Port A bit 1, for example and PTC5 is Port C bit 5, and so on
VREFH and VREFL are the ADC's voltage reference pins (high [highest level reference] and low [lowest level reference])
IRQ is the interrupt function that some pins can be programmed to have.
KBI0_Px is the keyboard interface function that a pin can be programmed to have.

There is then a chapter detailing each module.
