KL02 series MCU is no LLWU module , Can i use LPTMR interrupt to reset MCU in VLLS1 mode, if it is OK, how to config ?
Also, the source code available on the website FRDM is not driven SPI modules , can i use MKL05 FRDM SPI code for MKL02?
please see KL02 Sub-Family Reference Manual
VLLS1 only support RESET pin wakeup.
Thank you for your post, however please consider moving it to the right community place (e.g. Kinetis Microcontrollers ) to get it visible for active members.
For details please see general advice The specified item was not found.
Thank you for using Freescale Community.
KL02 don't have Low-Leakage Wake-up Unit (LLWU) module, so you don't use LPTMR interrupt to wakeup MCU in VLLS1 mode.
Thank you very much for your focus on Freescale Kinetis product. I am glad to provide service for you.
I've had a go through the KL02's RM and it says the LPTMR interrupt can be used to generate a wakeup from any low-power mode, including the low-leakage modes.
I'd like to suggest that you can through the link below to download the FRDM-KL02's demo code which include a lowpower mode code. Wish my support can support.
Have a nice day!!
I had download the source code http://cache.freescale.com/files/32bit/software/KL02-SC.zip
