Figure 33 and its associated notes on Pg 113 of the data sheet show/state 1uf caps should be placed as close as possible to the VDD pins, this implies they should be placed closer to the pins than the 0.1uf caps. Typically the smaller value decoupling capacitors (in this case the 0.1uF & 10nF) are placed closest to pins to provide better higher frequency PDN performance. Can you please double check that the data sheet decoupling cap placement recommendations are correct, and if so what's the rationale for this atypical placement?
Thanks -John
