Hi-Speed USB peripheral controller
In EOT-only mode, DIS_XFER_CNT must be set to logic 1. Although the DMA transfer
counter can still be programmed, it will not have any effect on the DMA transfer. The DMA
transfer will start once the DMA command is issued. Any of the following three ways will
terminate this DMA transfer:
Detecting an external EOT
Detecting an internal EOT (short packet on an OUT token)
Issuing a GDMA stop command
There are three interrupts programmable to differentiate the method of DMA termination:
bits INT_EOT, EXT_EOT and DMA_XFER_OK in the DMA Interrupt Reason register. For
details, see Table 55.
Remark: The DMA bus defaults to 3-state, until a DMA command is executed. All the
other control signals are not 3-stated.
8.4.1 DMA Command register (address: 30h)
The DMA Command register is a 1-byte register (for bit allocation, see Table 44) 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.
