CHAPTER 12 10-BIT SUCCESSIVE APPROXIMATION TYPE A/D CONVERTER ( PD78F041x only)
The 10-bit successive approximation type A/D converter converts an analog input signal into a digital value, and
The A/D converter has the following function.
10-bit resolution A/D conversion
10-bit resolution A/D conversion is carried out repeatedly for one analog input channel selected from ANI0 to
ANI5. Each time an A/D conversion operation ends, an interrupt request (INTAD) is generated.
