i.MXRT 102x spread spectrum

How do I configure spread spectrum for the MIMXRT1021DAG5A? There is no CCM_ANALOG_PLL_SYS_SS register in the clocks tool to enable it. I have selected PLL2 and input some test values. The values appear to change the board.c file to match, but there is no way to enable this feature from the tools (that I have found). I am using:

MCUXpresso IDE v11.9.0 [Build 2144] [2024-01-05]

Just wanted to be sure I hadn't missed where this was set. The 1176 had support so thought the 102x series would as well.

Re: i.MXRT 102x spread spectrum

Hi @joshgentrycargt,

I'm afraid that currently there isn't any way of enabling the Spread Spectrum using Clocks Config. This would have to be enabled manually using the CCM_ANALOG_PLL_SYS_SS register.

Sorry for the inconvenience this may cause.

BR,
Edwin.
