In Input mode, pin can use on-chip
pullup resister by software.
A/D converter 8-channel analog
input pin
If pin is not used by A/D converter
input, can use to general-purpose
bidirectional pin.
Input voltage in ANI0 - ANI7 is
between Avref+ and VSS.

VCOL
AM band VCO frequency input pin
75
EO
Error output pin in PLL part (charge pump output)
If tuning freq. = VCO freq., EO pin is floating.
If tuning freq. > VCO freq., EO pin is high.
If tuning freq. = VCO freq., EO pin is low.
76
RESET
Chip reset pin. Reset is active high.
