what is CCM->LPCG[137]? (no clarify in mxrt1176 reference manual)

[auftrag2021]

Hardware: imxrt1170 EVK

IDE: MCUXpressor 11.7.1

SDK: 2.13.1

Issue: 

in the MIMXRT1176_cm7.h file, we see

but due to the imxrt1170 reference manual page 1531, we have this:

which means the LPCG only have 136+1 = 137 members. What is the "138" for?

I checked lpcg enum defintion in the fsl_clock.h, we see this:

What is meaning of the last member "kCLOCK_Uniq_Edt_I",  which is nowhere in user manual clarified...

Hi @auftrag2021,

You can disregard the extra LPCG clock gate you see with value 137, as it is reserved for NXP use only.
