8.9.2 Repeat sweep mode 0 operation description
(1) When an internal trigger is selected
The A-D converter starts conversion for the input voltage from the AN
conversion start bit is set to "1."
The A-D conversion of the input voltage from the AN
the 8-bit mode, or 59 cycles of φ
approximation register (conversion result) are transferred to the A-D register 0.
The operation to all selected analog input pins is performed.
The conversion result is transferred to the A-D register i each time each pin is converted.
The operation to all selected analog input pins is performed again.
The operation is performed repeatedly until the A-D conversion start bit is cleared to "0" by software.
