38.1.3.3 Stop Mode
Stop Mode is used for power management by the system mode management. When a request is made to
enter Stop Mode, the RLE_DEC block completes the action currently processed. Then the request is
acknowledged.
38.2 External signal description
RLE_DEC has no external signals.
38.3 Interrupt and DMA request signals
The interrupt and DMA request lines of the RLE_DEC module are mapped to the internal flags in the
DEC_RLE_ISR register.
38.4 Memory map and register definition
