Datasheet

• Support selectable trigger input to optionally reset or cause the counter to start or

stop incrementing

• Support the generation of hardware triggers when the counter overflows and per

channel

2.2.4 ADC

this device contains one ADC module. This ADC module supports hardware triggers

from TPM, LPTMR, PIT, RTC, external trigger pin and CMP output. It supports

wakeup of MCU in low power mode when using internal clock source or external

crystal clock.

ADC module has the following features:

• Linear successive approximation algorithm with up to 16-bit resolution

• Up to four pairs of differential and 17 single-ended external analog inputs

• Support selectable 16-bit, 13-bit, 11-bit, and 9-bit differential output mode, or 16-

bit, 12-bit, 10-bit, and 8-bit single-ended output modes

• Single or continuous conversion

• Configurable sample time and conversion speed/power

• Selectable clock source up to four

• Operation in low-power modes for lower noise

• Asynchronous clock source for lower noise operation with option to output the

clock

• Selectable hardware conversion trigger

• Automatic compare with interrupt for less-than, greater-than or equal-to, within

range, or out-of-range, programmable value

• Temperature sensor

• Hardware average function up to 32x

• Selectable voltage reference: external or alternate

• Self-Calibration mode

VREF

The Voltage Reference (VREF) can supply an accurate voltage output (1.2V typically)

trimmed in 0.5 mV steps. It can be used in applications to provide a reference voltage

to external devices or used internally as a reference to analog peripherals such as the

ADC, DAC or CMP.

The VREF supports the following programmable buffer modes:
