12. 8/10-bit A/D converter
The A/D converter converts analog input voltages into digital values and has the following features.
RC sequential compare conversion method with sample and hold circuit
Selectable 8-bit resolution or 10-bit resolution
Analog input program-selectable from among 16 channels
Single conversion mode : Convert 1 selected channel
Scan conversion mode : Continuous plural channels (maximum 16 channels can be programmed) are converted.
Continuous conversion mode : Repeatedly convert the specified channels.
Stop conversion mode: Convert 1 channel then suspend conversion to remain on standby until the next
activation. (Simultaneous conversion start available.)
An interrupt request to the CPU can be generated upon completion of A/D conversion. Suitable for continuous
processing as this interrupt activates
μ
DMA to transfer the data resulting from A/D conversion to memory.
The activation source can be selected from among software, external trigger (falling edge), and timer (rising
edge).
