stopped, if it was started by means of hardware, after the conversion is complete, and an interrupt request (INTAD0)
is generated. When A/D conversion is started by software, conversion is repeatedly performed. Each time conversion
is completed once, INTAD0 is generated.
11.2 Configuration of A/D Converter
202
The A/D converter converts analog input signals into digital values, and consists of eight channels (ANI0 to ANI7)
This A/D converter is of successive approximation type, and the result of conversion is held by 10-bit A/D conversion
A/D conversion can be started in the following two ways.
(1) Hardware start
(2) Software start
One analog input channel is selected from ANI0 to ANI7 and A/D conversion is executed. A/D conversion is
The A/D converter includes the following hardware.
Conversion is started by trigger input (ADTRG; rising edge, falling edge, or both rising and falling edges can
be specified).
Conversion is started by setting A/D converter mode register 0 (ADM0).
