20180718 Wey recommend
20180718 follow NV circuit
20180718 follow NV circuit
20180718 follow NV circuit
Prevent while IC initial,
1V8_AON_EN unstable
20180718 follow NV circuit
20180725 Use for NVVDD_PWRGD
20180725 Add FGC6
20180731 Rsvd.
20180802 change from IFPF to IFPB
20180802 change from IFPF to IFPB
D02 1005 pin17, 18 swap
Optimize doesn't have FGC6 function
