13. 8/10-bit A/D Converter
The 8/10-bit A/D converter uses RC successive approximation to convert analog input voltages to an 8-bit or
10-bit digital value.
The input signals can be selected from the eight analog input pin channels.
Either a software trigger, internal timer output, or external pin trigger can be selected to trigger the start of A/
D conversion.
8/10-bit A/D converter functions
8/10-bit A/D converter conversion modes
Function
A/D conversion
time
Sampling time : Can be selected from 64, 128, or 4096 machine cycles.
The minimum is 4
s.
Compare time : Can be selected from 44, 99, or 176 machine cycles.
The minimum is 4.4
s.
A/D conversion time = sampling time + conversion time.
The minimum A/D conversion time is 10.2
s.
Conversion method
RC successive approximation with sample & hold circuit
Resolution
8-bit or 10-bit, selectable
Analog input pins
Up to eight channels can be used. However, two or more channels cannot be used
simultaneously.
Interrupts
An interrupt request can be generated when A/D conversion completes.
A/D conversion
start trigger
Selectable : software, internal timer output, or falling edge on input from external pin
EI2OS support
Supported by the extended intelligent I/O service (EI2OS) .
Description
Single-shot
conversion mode
Performs A/D conversion sequentially from the start channel to the end channel. A/D con-
version halts after conversion completes for the end channel.
Continuous
conversion mode
Performs A/D conversion sequentially from the start channel to the end channel. A/D con-
version starts again from the start channel after conversion completes for the end channel.
Incremental
conversion mode
A/D conversion is performed for one channel then halts until the next trigger. After conver-
sion is performed for the end channel, the next conversion is performed for the start chan-
nel, and repeated this operation.
