Hi wang,

SIM_PINSEL1[FTM2PS5] used to select the FTM2 channel 5 pinout.

SIM_PINSEL1[FTM2PS1] used to select the FTM2 channel 1 pinout.

You can find it in the KE04 reference manual, chapter SIM.

Wish it helps you!

Have a great day,
Kerry

hi kerry,

thanks for your kindly response .

but i already check the RM (MKE04P24M48SFORM.pdf) , there is not the pinsel1 register .

and still i have checked the library , also no pinsel1 .

i only found the pinsel1 in the KE06 RM .

so what i want to know , whether the FTM2_CH5 working for KE04 ? and if yes , how to use it .

thanks again .

Hi Wangwang,

Sorry, my fault, I refer to the wrong reference manual:MKE04P80M48SF0RM.pdf before.

Your chip is KE04z8, so you should refer to MKE04P24M48SF0RM.pdf.

But don't worry, because there only one FTM2_CH5(PTB5) and FTM2_CH1(PTC1), then you don't need to use the register to choose the multiplex pin. When you enable the FTM2 channel 5, PTB5 is the FTM2_CH5 pin; When you enable the FTM2 channesl 1, PTC1 is the FTM2_CH1 pin.

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.

ALT0 is the lowest priority, and ALT7 is the highest priority.

Wish it helps you!

If you still have question, please let me know!

Have a great day,
Kerry
