10.4.3 A/D converter operation modes
(1) Software trigger mode (Continuous conversion mode)
R01UH0004EJ0401 Rev.4.01
Jul 2, 2010
The following four A/D converter operation modes are available.
• Software trigger mode (Continuous conversion mode)
• Software trigger mode (Single conversion mode)
• Timer trigger mode (Continuous conversion mode)
• Timer trigger mode (Single conversion mode)
