4. 10-bit 8-channel A/D Converter (with 8-bit Resolution Mode)
The 10-bit 8-channel A/D converter converts analog input voltage into a digital value. The features of this module
are as follows:
Conversion time: Minimum of 6.13
μ
s per channel (98 machine cycles/16 MHz machine clock, including
sampling time)
Sampling time: Minimum of 3.75
μ
s per channel (60 machine cycles/16 MHz machine clock)
RC-type successive approximation conversion method with sample and hold circuit
10-bit/8-bit resolution
Analog input is selectable by software from among 8 channels
Single-conversion mode: Selects and converts one channel.
Scan conversion mode: Converts several consecutive channels (up to eight channels can be programmed).
Continuous conversion mode: Repeatedly converts the specified channel.
Stop conversion mode: Pauses after converting one channel and waits until the next activation (permits
synchronization of start of conversion).
When A/D conversion is completed, an “A/D conversion complete” interrupt request can be issued to the CPU.
Because generating this interrupt can be used to activate the I
2
OS and transfer the A/D conversion results to
memory, this function is suitable for continuous processing.
Activation sources can be selected from among software, an external trigger (falling edge), and 16-bit reload
timer 1 (rising edge).
