Hi @bennxp ,
Thanks for your interest in NXP MIMXRT series!
The official documentation does not provide a hardware development manual specific to the RT1060X. Regarding NVCC_SPIX, these are new, independent power domains that support either 1.8V or 3.3V. For the selection of decoupling capacitors, refer to NVCC_GPIO; please do not skimp on capacitors. There are no special requirements regarding power-up sequencing.
Best regards,
Gavin
