Why is ClrValue() not working?

[cmcc]

I am having trouble with the PPG1_ClrValue().  First I use PPG1_Disable().  That works fine.  However, when I use PPG1_ClrValue(), nothings happens.  It is the same with PPG1_SetValue().  Why are these not working?

Hi,

This PPG component works with the FTM module as the counter module or another timer and the methods SetValue and ClearValue are only valid when the module is disabled, the necessary sequence to use them is:

Disable();

ClearValue();
Enable();

Or

Disable();

SetValue();
Enable();

These methods do not write to the duty register, this means that the value of the counter for each channel remains the same after calling these methods. The methods only write to the register that changes the initial value of the channel.

I hope this information can help you.

Regards,

Adrian

Adrian,

I am aware of this.  However, my PPG signal is high even when I try to clear it.  I cannot make it low.

Sincerely,
