Function

Description

A/D converter

A/D

converter

(ADC)

• 10-bit resolution × two units

• Selectable input channel and unit configuration

Four channels

× two units (units 0 and 1)

Eight channels

× one unit (unit 0)

• Sample and hold function included

• Conversion time: 2.7 µs per channel (with peripheral module

clock (P

φ) at 25-MHz operation)

• Two operating modes: single mode and scan mode

• Three ways to start A/D conversion:

Unit 0: Software, timer (TPU (unit 0)/TMR (units 0 and 1))

trigger, and external trigger

Unit 1: Software, TMR (units 2 and 3) trigger, and external

trigger

• Activation of DTC and DMAC by ADI interrupt:

Unit 0: DTC and DMAC can be activated by an ADI0 interrupt.

Unit 1: DMAC can be activated by an ADI1 interrupt.

D/A converter

D/A

converter

(DAC)

• 8-bit resolution × two output channels

• Output voltage: 0 V to Vref, maximum conversion time: 10 µs

(with 20-pF load)

Timer

8-bit timer

(TMR)

• 8 bits × eight channels (can be used as 16 bits × four channels)

• Select from among seven clock sources (six internal clocks and

one external clock)

• Allows the output of pulse trains with a desired duty cycle or

PWM signals
