11.1.2 Operation Modes
The A-D converters operate in two modes: "Single mode" and "Scan mode."
(1) Single mode
In single mode, the analog input voltage in one selected channel is A-D converted once or
comparated with a given quantity. An A-D conversion interrupt request or a DMA transfer request
(for the A-D0 converter only) can be generated at completion of A-D conversion.
Figure 11.1.3 Operation in Single Mode (A-D Conversion)
Figure 11.1.4 Operation in Single Mode (Comparate)
Note 1: A-D0 conversion start: Software trigger
→
Started by setting A-D0 conversion start bit to 1
____________
Hardware trigger
→
Started by output event bus 3 or ADTRG signal input
A-D1 conversion start: Software trigger
→
Started by setting A-D1 conversion start bit to 1
____________
Hardware trigger
→
Started by TID1 overflow/underflow or ADTRG signal input
Note 2: DMA transfer request: Can be generated for only the A-D0 converter.
Note 1: Comparate start: Started by writing a comparison value to the successive approximation register (ADiSAR)
Note 2: DMA transfer request: Can be generated for only the A-D0 converter.
