TPM timer initial delay when using 32kHz EXTAL

I'm trying to use TPM clock on KL17 using external 32kHz crystal. I've initialized MOD value with 32, so expecting it to interrupt after 1ms.


But I always get the first interrupt from tpm counter after 120ms delay, subsequent interrupts happen at 1ms interval.


Any pointers to debugging this issue?
