Description
 1 channel
 Acquisition of synchronization through external 8-bit horizontal and vertical
synchronization signals
 Setting of the image size when clipping of the output for a one-frame image is required
 12 bits × 2 units (unit 0: 8 channels; unit 1: 21 channels)
 12-bit resolution (switchable between 8, 10, and 12 bits)
 Conversion time
0.48 μs per channel (for 12-bit conversion)
0.45 μs per channel (for 10-bit conversion)
0.42 μs per channel (for 8-bit conversion)
 Operating mode
Scan mode (single scan mode, continuous scan mode, or group scan mode)
Group A priority control (only for group scan mode)
 Sample-and-hold function
Common sample-and-hold circuit included
In addition, channel-dedicated sample-and-hold function (3ch: in unit 0 only) included
 Sampling variable
Sampling time can be set up for each channel.
 Digital comparison
Method: Comparison to detect voltages above or below thresholds and window
comparison
Measurement: Comparison of two results of conversion or comparison of a value in the
comparison register and a result of conversion
 Self-diagnostic function
The self-diagnostic function internally generates three analog input voltages (unit 0:
VREFL0, VREFH0 × 1/2, VREFH0; unit 1: AVSS1, AVCC1 × 1/2, AVCC1)
 Double trigger mode (A/D conversion data duplicated)
 Detection of analog input disconnection
 Three ways to start A/D conversion
Software trigger, timer (MTU3, GPT, TMR, TPU) trigger, external trigger
 Event linking by the ELC
 2 channels
 12-bit resolution
 Output voltage: 0.2 V to AVCC1 0.2 V (amplifier output), 0 V to AVCC1 (direct output)
 Output via an amplifier or direct output can be selected.
 Event linking by the ELC
 1 channel
 Relative precision: ±1°C
 The voltage of the temperature is converted into a digital value by the 12-bit A/D
converter (unit 1).
