ADCMS35B_000020020700
Single mode: Single-channel A/D conversion
Scan mode: Continuous A/D conversion on 1 to 4 channels
Conversion results are held in a 16-bit data register for each channel.
Software
16-bit timer pulse unit (TPU or TMR) conversion start trigger
External trigger signal
An A/D conversion end interrupt request (ADI) can be generated.
The range of voltages of analog inputs to be converted can be specified using the Vref signal
as the analog reference voltage.
