TPM channel mode changes

Does anyone know what the phrase "acknowledged in the LPTPM counter clock domain" mean?


I am using a KL25 microcontroller (in the FRDM-KL25Z board) and that phrase is used in the datasheet when talking about changing the MSB:MSA and ELSB:ELSA bits in the TPMx_CnSC register for changing TPM channel modes.


From the tests I've made, I am assuming that it means that the change in the bits will not take effect until the TPM counter passes through 0, either going from MOD or CnV to 0, or going from 1-0-1 when using up-down counting (this is my case in particular).


Does anyone know for sure?
