PWR
+1.8V supply to the internal clock multiplier. This pin
requires a 100nF decoupling capacitor.
* 48 pin LQFP package only – This power input is internally
connected to VREG_OUT.
All other packages need this pin connected to a 1.8V power
source. Most common applications will connect this to
VREG_OUT.

VCCIO
PWR
+3.3V supply to the input / output. Interface pins
(IOBUS). Leaving the VCCIO unconnected will lead to
unpredictable operation on the interface pins.
