Section 11 A/D Converter
11.2 Input/Output Pins
Table 11.1 summarizes the input pins used by the A/D converter. The SH7108 has three A/D
conversion modules and the SH7109 two A/D conversion modules, each of which can be operated
independently. The input channels are divided into four channel sets.
The analog input pins that can be used differ in each product type, as shown in table 11.1.
