Peripheral Events
Sleep Mode
Conversion Performances
The Peripheral Event System can be used together with the ADCIFB to allow any peripheral
event generator to be used as a trigger source. To enable peripheral events to trigger a conver-
sion sequence the user must write the Peripheral Event Trigger value (0x7) to the Trigger Mode
(TRGMOD) field in the Trigger Register (TRGR). Refer to
must also configure a peripheral event generator to emit peripheral events for the ADCIFB to
trigger on. Refer to the Peripheral Event System chapter for details.
Before entering sleep modes the user must make sure the ADCIFB is idle and that the Analog-
to-Digital Converter cell is inactive. To deactivate the Analog-to-Digital Converter cell the SLEEP
bit in the ADC Configuration Register (ACR) must be written to one and the ADCIFB must be
idle. To make sure the ADCIFB is idle, write a zero the Trigger Mode (TRGMOD) field in the
Trigger Register (TRGR) and wait for the READY bit in the Status Register (SR) to be set.
Note that by deactivating the Analog-to-Digital Converter cell, a startup time penalty as defined
in the STARTUP field in the ADC Configuration Register (ACR) will apply on the next
conversion.
For performance and electrical characteristics of the ADCIFB, refer to the Electrical Characteris-
tics chapter.
