Hi,

 

I want to upgrade KL27 based project with new K32L2A (same 64 LQFP package and pinout), to have higher speed and more Flex IO shift / timer.

 

KL27 is working on 48 MHz CPU clock with 24 MHz flash clock. Each assembler register operation executing from flash will take one CPU cycle. Port access that is in CPU domain (IOPORT) will take one CPU cycle.

 

I want to know what will be situation with K32L2A with HSRUN 96 MHz CPU clock (and 24 MHz flash clock). Assembler register operation executed from flash will take one CPU cycle? IOPORT access will take one CPU cycle? What is downside of running in HSRUN mode except higher current consumption?

 

Thank you,

Josip
