3.3-V Flash Core Power Pin. This pin should be connected to
3.3 V at all times after power-up sequence requirements have
been met. This pin is used as VDDIO in ROM parts and must
be connected to 3.3 V in ROM parts as well.
Typical drive strength of the output buffer for all pins is 4 mA except for TDO, XCLKOUT, XF, XINTF, EMU0, and EMU1 pins, which are 8 mA.
I = Input, O = Output, Z = High impedance
§ PU = pin has internal pullup; PD = pin has internal pulldown. Pullup/pulldown strength is given in Section 6.3.
