nRF54L15 NRF_TIMER clock source(PCLK)

[loquat]

Hello.

The nRF54L15 datasheet states that the source clock for NRF_TIMER is PCLK.
By the way, it seems that there are PCLK32M/PCLK16M/PCLK1M for PCLK. Which one is used?

Hi,

As you mention it can be either PCLK32M, PCLK16M, or PCLK1M, depending on the specific TIMER instance and the configured timer frequency. The TIMER configuration table at https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/timer.html#d1770e585 shows that different TIMER instances have different peripheral clock frequencies.

Kind regards,
Andreas

Oh, OK.

Thanks.
