HARDWARE
1.15 A-D Converter
The 7480 Group and 7481 Group have a built-in A-D converter with:
• analog input pins ...................... 8 channels (alternative functions of port P2) (Note), and
• conversion system .................... 8-bit successive comparison.
When the A-D converter is not used, power dissipation can be reduced by clearing the VREF connection
selection bit of the A-D control register to ‘0’ and switching off VREF.
Note: In the 7480 Group, 4-channel analog input pins are implemented.
