Hello! I am currently writing a C code about the MC9S08DZ60 controller running in STOP2 mode! Mainly, after power on, it enters STOP2 mode, and then wakes up and lights up the LED small light through the external button of the IRQ pin! But I don't know how to get started. I looked at the low-power documentation of AN3387, but it's all assembly code, and I only know C language! So I would like to request a case study of C language programming from you! Thank you!
