PSoC 4 MCU

Which of these methods yields the most accurate result ?

Calling CySysClkIloTrim( CY_SYS_CLK_BLOCKING, &iloAccuracyInPPT )

should ensure that the ILO is within -10/+10 % accuracy.

But does using the compensate method yield a more accurate result using the compensation value as timer match value ?

I want to get the must accurate timing possible for my WDT timer based on the ILO as LFCLK source.

Hi Martin,

compensating WDT match values could be a better way. Refer CE210292 in PSoC Creator.
