Which is the boot pin for MKL16Z128VLH4 Kinetis KL16 MCU.

I can only see the reset pin in datasheet.

Are reset pin and boot pin the same?

Let us know which is the boot pin?

Hi,

For the Kinetis KL16, there is not regular boot mode, I mean that you can not download application binary to flash via uart, spi...for KL16.

The KL16 will execute code in flash directly after Reset, but you can write the 0x0_040D(Flash top address) so that you can configure the core clock, enable/disable the Reset pin and NMI pin...

For detailed inf, pls refer to section 27.3.1 Flash Configuration Field Description and section 6.3.2 FOPT boot options in the RM of Kl16.

In conclusion, there is Reset pin, there is not BOOT pin.

Hope it can help you
