Note:

V33 and V33IO-PLL are all internally connected. Same for VSS and VSSIO-PLL.

All VSS, VSS18, VSSBKP, AVSS,VSSRF,VSSRF_A and VSSRF_IO pins must be tied together to the

common ground plane, taking care of noise filtering, especially on AVSS ,VSSRF , VSSRF_A

and VSSRF_IO

VSSBKP

Digital ground for backup logic

AVDD
