13. A/D Converter
The converter converts the analog voltage input to an analog input pin (input voltage) to a digital value. The
converter has the following features :
The minimum conversion time is 6.13
μ
s (for a machine clock of 16 MHz; includes the sampling time) .
The minimum sampling time is 2.0
μ
s (for a machine clock of 16 MHz) .
The converter uses the RC-type successive approximation conversion method with a sample hold circuit.
A resolution of 10 bits or 8 bits can be selected.
Up to eight channels for analog input pins can be selected by a program.
Various conversion mode :
- Single conversion mode : Selectively convert one channel.
- Scan conversion mode : Continuously convert multiple channels. Maximum of 8 program selectable channels.
- Continuous conversion mode : Repeatedly convert specified channels.
- Stop conversion mode : Convert one channel then halt until the next activation. (Enables synchronization of
the conversion start timing.)
At the end of A/D conversion, an interrupt request can be generated and EI
2
OS can be activated.
In the interrupt-enabled state, the conversion data protection function prevents any part of the data from being
lost through continuous conversion.
The conversion can be activated by software, 16-bit reload timer 1 (rising edge) and 16-bit free-running timer
zero detection edge.
