SAM4L Datasheet, PDF (924/1185 Pages) ATMEL Corporation – ATSAM ARM-based Flash MCU

ATSAM4L4/L2
• ETRIG: Event Triggered Operation
0: Normal continuous acquisition mode of operation.
1: CATB acquisitions are triggered by the Peripheral Event System.
• IIDLE: Initialize Idle Value
0: The IDLE register will only be updated by the CATB, or if written to.
1: The IDLE register is set to the next measured value.
This bit always reads as zero.
• RUN: Start Operation
Writing a zero to this bit will stop the CATB.
Writing a one to this bit will usually start acquisitions immediately. If CR.DMAEN is one, the CATB will wait until the first DMA
transfer. If CR.ETRIG is one, the CATB will wait for a peripheral event.
0: CATB is stopped.
1: CATB is running.
• EN: Access Enable
0: The CATB interface is disabled, register configuration settings can not be changed.
1: The CATB interface is enabled, register configuration settings can be changed.
