reexecuted from the beginning.
When in single mode, set the A-D Single Mode Register 0 A-D conversion start bit to "1" again or enter a
hardware trigger during A-D conversion or comparate operation, and the operation that was stopped during
execution is executed over again.
When in scan mode, set the A-D Scan Mode Register 0 A-D conversion start bit to "1" again or enter a
hardware trigger signal during scan operation, and the channel being converted is canceled and A-D conver-
sion is performed from channel 0 over again.
