FRDM-KL03Z in KDS: Can't Set the MS0A Bit Register

[sarastout-grand]

I am using the following line of code to set the MS0A bit:     TPM_BWR_CnSC_MSA(tpmbase,0,1);

This does not seem to work. As a result I can't get into Output compare mode. Any suggestions? I set the  ELS0A bit in the same manner (TPM_BWR_CnSC_ELSA(tpmbase,0,1);) and that works just fine.

What am I doing wrong?

Hello Sara,

Could you please show your project,

or share a simple project which I can reproduce the problem on my side.

Hi Alice,

I figured it out. Apparently, you can’t set the individual bits in the CnSC register…you have to set them all at once. When I did that, the MS0A bit would set properly.

Thanks anyway!
