ADCMS04A_010020020300
Single mode: Single-channel A/D conversion
Scan mode: Continuous A/D conversion on 1 to 4 channels or 1 to 8 channels
Conversion results are retained in a 16-bit data register for each channel
Conversion can be started by software, conversion start trigger by 16-bit timer pulse unit
(TPU) or 8-bit timer (TMR), or external trigger signal.
A/D conversion end interrupt (ADI) request can be generated
