This LSI includes a ∆Σ modulation-type 16-bit ∆Σ A/D converter. This module accepts up to six
analog inputs, each of which is internally amplified eight-fold and then sequentially converted by
time-division multiplexing.
A block diagram of the ∆Σ A/D converter is shown in figure 19.1.
• 16-bit resolution
• Suitable for sensor applications (cannot be applied to voice and audio applications)
• Conversion method: ∆Σ modulation-based conversion
• Six input channels (time-division multiplexing)
• Two types of input channel (four single-ended channels and two differential input channels)
• Conversion time: 91.5 µs per channel
• Six data registers
• Three ways of starting A/D conversion
• Interrupt source
• Can be placed in the module stop state
Note: * Initiation of conversion by a TPU/TMR trigger is available with the on-chip emulator

19.1
Offset cancellation by 10-bit DAC on single-ended channels
(for 286-“state” conversion at Aφ = 25 MHz, where 1 state = Aφ/8)
Results of A/D conversion are stored in 16-bit registers for the respective channels.
 Software
 Trigger from the 16-bit timer pulse unit (TPU)* or 8-bit timer (TMR)*
 External trigger signal
Generates ∆Σ A/D conversion end interrupt requests (DSADI).
Features
but not with other emulators.
