Hi-Speed USB peripheral controller
Remark: The DMA bus defaults to 3-state, until a DMA command is executed. All the
other control signals are not 3-stated.
9.4.1 DMA Command register (address: 30h)
The DMA Command register is a 1-byte register (for bit allocation, see Table 51) that
initiates all DMA transfer activity on the DMA controller. The register is write-only: reading
it will return FFh.
Remark: The DMA bus will be in 3-state, until a DMA command is executed.
