Table 15-16. DMA Hardware Request Status (DMAHRSH, DMAHRSL) field descriptions
Name
HRSn,
n = 0,... 15
n = 0,... 31
n = 0,... 63
Description
DMA Hardware Request Status n
Value
0 A hardware service request for channel n is not
present.
1 A hardware service request for channel n is present.
Note: The hardware request status reflects the state of
the request as seen by the arbitration logic.
Therefore, this status is affected by the
DMAERQn bit.
15.2.1.16 DMA General Purpose Output Register (DMAGPOR)
The optional DMAGPOR register provides a general purpose register in the programmer’s model that
ouputs the register contents. The DMAGPOR performs no functions within the DMA2. This general
purpose register is enabled when SPP_DMA2_ENABLE_GPOR is defined. This register may be used by
the SoC integrator to define and display configuration information.
See Figure 15-17 and Table 15-17 for the DMAGPOR definition.
