22.2
Table 22.1 summarizes the pins used by the A/D converter. The 8 analog input pins are divided
into two groups consisting of four channels. Analog input pins 0 to 3 (AN0 to AN3) comprising
group 0 and analog input pins 4 to 7 (AN4 to AN7) comprising group1.
Note that this LSI does not provide the AN0 and AN1 pins. Expanded A/D conversion input pins
(CIN0 to CIN7) can be used instead of AN0. The AVCC and AVSS pins are the power supply
pins for the analog block in the A/D converter.
