10-bit resolution
Analog conversion voltage range can be specified using the reference power supply voltage
pin (AVref) as an analog reference voltage.
Conversion time: 13.4 µs per channel (at 10-MHz operation)
Two kinds of operating modes
Four data registers
Sample and hold function
Three kinds of conversion start
Interrupt request
nput channels: eight analog input channels and 16 digital input channels
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, 8-bit timer (TMR) conversion start trigger, or external trigger signal.
A/D conversion end interrupt (ADI) request can be generated
