How to enable port clock in ke02z64xxx2 processor?

Hi guys

I want to enable the port clock in KE02Z64xxx2 processor. I read the datasheet but i found nothing.Is it necessary to enable the port clock? If yes how to do that?

In KL25z series there is a register SIM_SCGC5, using this we can enable n disable the clock of certain port.

KE02 doesn't have a clock gate for its GPIOs so you don't need to do anything before using them.

Hi Abdul Hayee,

In KL25z series there is a register SIM_SCGC5, using this we can enable n disable the clock of certain port.

But I am sorry to tell you that there are no Clock Gating Control Register for KE02 series.

There are no PORTx_PCRn[MUX] for KE02 series either.

So please notice: Many of the I/O pins are shared with on-chip peripheral functions. The peripheral modules have priority over the I/O, so when a peripheral is enabled, the associated I/O functions are disabled.

Best Regards,

Robin
