About unused NVCC18_IO in i.MX6SL.

Dear Sir or madam,



If one doesn't use the 1.8V voltage in i.MX6SL system, is it necessary to input 1.8 V to NVCC18_IO? (Or, is it ok the NC?)



Refer to (P.73) 7.2.4 Power-up sequence in low voltage system design in i.MX6SL HardwareDevelopmentGuide Rev1.

If one use the 3.15V(NVCC33_IO) for all logic IO, is it possible to ignore the Sect 7.2.4?


Best Regards
