This LSI includes a successive approximation type 10-bit A/D converter that allows up to eight
analog input channels to be selected.
Figure 15.1 shows a block diagram of the A/D converter.
15.1
• 10-bit resolution
• Eight input channels
• Conversion time: 7.4 µs per channel (at 35-MHz operation)
• Two kinds of operating modes
• Eight data registers
• Sample and hold function
• Three types of conversion start
• Interrupt source
• Module stop state specifiable
 Single mode: Single-channel A/D conversion
 Scan mode: Continuous A/D conversion on 1 to 4 channels, or 1 to 8 channels
A/D conversion results are held in a 16-bit data register for each channel
Conversion can be started by software, a conversion start trigger by the 16-bit timer pulse unit
(TPU) or 8-bit timer (TMR), or an external trigger signal.
A/D conversion end interrupt (ADI) request can be generated.
