KL15: Missing [PLLFLLSEL] bits in SIM_SOPT2?

[Safwat]

I am trying to route the output of the PLL to clock the UART0. In the ref manual, chapter 5 page 117, clocking options for UART0 are shown as below:

But I could not find PLLFLLSEL bits in the SIM_SOPT2. The description of SIM_SOPT2 is shown as below (Section 12.2.3 page 186):

Anyone know are these bits implemented for KL15 chips?

thanks!

Thanks Paul. Good to know its there :smileyhappy:

Hi, Safwat

This is a document issue. The bit 16 in register SIM_SOPT2 is PLLFLLSEL.

Hope my reply can help you.

Best Regards

The SIM_SOPT2_PLLFLLSEL bit is also missing in Processor Expert generated file (IO_Map.h):
