(3) Block Diagram
(4) Precautions for Use:
When the A/D converter is started from an external trigger or internal timer, the ADCS register A/D start source
bits STS1, STS0 are set, and at this time the input values for the external trigger and internal timer should be
set to the inactive side. If these values are set to the active side, abnormal operation may result.
When setting the STS1, STS0 bits, set ATG = “1” input, reload timer (channel 2) = “0” output.
value sampling within the specified sampling time, so that proper results will not be obtained.
