I'm trying to configure clocks for an LPCXpresso54018, SDK version is: SDK Version: KSDK 2.4.2 (2018-09-14).
I want to configure the FRG_clock.
The value for FRGCTRL_MUL is set to *256, and can't be changed. It's only possible to set FRGCTRL_DIV.
From the LPC540xx reference manual, it looks like FRGCTRL_DIV should always set to 0xff. But i should be able to set FRGCTRL_MUL.
I've added screenshots showing the dropdown menu's for both settings.
Am i doing something wrong? Or is it a problem in clocks tool?
