Description

Mode Register

Fields

TRGEN

Trigger Enable

0 (DIS): Hardware triggers are disabled. Starting a conversion is only possible by software.

1 (EN): Hardware trigger selected by TRGSEL field is enabled.

TRGSEL

Trigger Selection

0 (ADC_TRIG0): External trigger

1 (ADC_TRIG1): TIO Output of the Timer Counter Channel 0

2 (ADC_TRIG2): TIO Output of the Timer Counter Channel 1

3 (ADC_TRIG3): TIO Output of the Timer Counter Channel 2

LOWRES

Resolution

0 (BITS_10): 10-bit resolution

1 (BITS_8): 8-bit resolution

SLEEP

Sleep Mode

0 (NORMAL): Normal Mode: The ADC Core and reference voltage circuitry are kept ON between conversions

1 (SLEEP): Sleep Mode: The ADC Core and reference voltage circuitry are OFF between conversions

FWUP

Fast Wake Up

0 (OFF): Normal Sleep Mode: The sleep mode is defined by the SLEEP bit

1 (ON): Fast Wake Up Sleep Mode: The Voltage reference is ON between conversions and ADC Core is OFF

FREERUN

Free Run Mode

0 (OFF): Normal Mode

1 (ON): Free Run Mode: Never wait for any trigger.

PRESCAL

Prescaler Rate Selection

STARTUP

Start Up Time

0 (SUT0): 0 periods of ADCClock

1 (SUT8): 8 periods of ADCClock

2 (SUT16): 16 periods of ADCClock

3 (SUT24): 24 periods of ADCClock

4 (SUT64): 64 periods of ADCClock

5 (SUT80): 80 periods of ADCClock

6 (SUT96): 96 periods of ADCClock

7 (SUT112): 112 periods of ADCClock

8 (SUT512): 512 periods of ADCClock

9 (SUT576): 576 periods of ADCClock

10 (SUT640): 640 periods of ADCClock

11 (SUT704): 704 periods of ADCClock

12 (SUT768): 768 periods of ADCClock

13 (SUT832): 832 periods of ADCClock

14 (SUT896): 896 periods of ADCClock

15 (SUT960): 960 periods of ADCClock

TRACKTIM

Tracking Time

USEQ

Use Sequence Enable

0 (NUM_ORDER): Normal Mode: The controller converts channels in a simple numeric order.

1 (REG_ORDER): User Sequence Mode: The sequence respects what is defined in ADC_SEQR1 and ADC_SEQR2 registers.
