Memory map/register definition
21.3.15 Hardware Request Status Register (DMA_HRS)
The HRS provides a bit map for the DMA channels, signaling the presence of a hardware
request for each channel. The hardware request status bits reflect the current state of the
register and qualified (via the ERQ fields) DMA request signals as seen by the DMA’s
arbitration logic. This view into the hardware request signals may be used for debug
purposes.
Address: DMA_HRS is 4000_8000h base + 34h offset = 4000_8034h

These bits reflect the state of the request as seen by the
arbitration logic. Therefore, this status is affected by the ERQ
bits.
