6.1.8 Enabled Channel Register (DMACEnbldChns - 0xFFE0 401C)
6.1.9 Software Burst Request Register (DMACSoftBReq - 0xFFE0 4020)
Table 659. Raw Error Interrupt Status register (DMACRawIntErrorStatus - address
The DMACEnbldChns Register is read-only and indicates which DMA channels are
enabled, as indicated by the Enable bit in the DMACCxConfiguration Register. A HIGH bit
indicates that a DMA channel is enabled. A bit is cleared on completion of the DMA
transfer.
Table 660. Enabled Channel register (DMACEnbldChns - address 0xFFE0 401C) bit
The DMACSoftBReq Register is read/write and enables DMA burst requests to be
generated by software. A DMA request can be generated for each source by writing a 1 to
the corresponding register bit. A register bit is cleared when the transaction has
completed. Writing 0 to this register has no effect. Reading the register indicates which
sources are requesting DMA burst transfers. A request can be generated from either a
peripheral or the software request register.
DMACSoftBReq Register.
Table 661. Software Burst Request register (DMACSoftBReq - address 0xFFE0 4020) bit
Note: It is recommended that software and hardware peripheral requests are not used at
the same time.
