TPM don't work well when MOD=1

hello,

 

I want to use TPM as a common timer, but met a confusing phenomenon, when MOD=1, the period is not right.

 

hardware:FRDM_KL43Z

 

TPM clock source is OSCERCLK(32.768Khz)

 

I toggle a gpio in TPM timer ISR, When MOD=1, the frequency is wrong.  It will be right if MOD set for other values.

 

Thanks.
