ADC External Reference High – only used when in ADC external reference mode. See
Section 6.9.2.1.
NOTE: V
REFHI
and ADCINA0 share the same pin on the 80-pin PN and PFP devices
and their use is mutually exclusive to one another.

V
REFLO
27 21
ADC External Reference Low.
NOTE: V
REFLO
is always connected to V
SSA
on the 80-pin PN and PFP devices.
CPU AND I/O POWER
V
DDA
25 20 Analog Power Pin. Tie with a 2.2-μF capacitor (typical) close to the pin.
V
SSA
26 21
Analog Ground Pin.
NOTE: V
REFLO
is always connected to V
SSA
on the 80-pin PN and PFP devices.
V
DD
3 2
CPU and Logic Digital Power Pins. When using internal VREG, place one 1.2-µF
capacitor between each V
DD
pin and ground. Higher value capacitors may be used.

V
DDIO
5 4
Digital I/O and Flash Power Pin. Single supply source when VREG is enabled. Place a
2.2-uF decoupling capacitor on each pin. The exact value of the total decoupling
capacitance should be determined by the system voltage regulation solution.
