Direct Memory Access (DMA)
9.2.1.15
The DMA Hardware Request Status High (DMAHRSH) and DMA Hardware Request Status Low
(DMAHRSL) registers provide a bit map for the implemented 64 channels’ current hardware request
status. DMAHRSH supports channels 63–32, while DMAHRSL covers channels 31–00. The hardware
request status reflects the current state of the registered and qualified (via the DMAERQ field) request
lines as seen by DMA arbitration logic. This view into the hardware request signals may be used for debug
purposes. See
