Hi-Speed USB peripheral controller
The DMA Endpoint register must not reference the endpoint that is indexed by the
Endpoint Index register (2Ch) at any time. Doing so will result in data corruption.
Therefore, if the DMA Endpoint register is unused, point it to an unused endpoint. If the
DMA Endpoint register, however, is pointed to an active endpoint, the rmware must not
reference the same endpoint on the Endpoint Index register.
9.4.9 DMA Strobe Timing register (address: 60h)
This 1-byte register controls the strobe timing for MDMA mode, when bits
DMA_MODE[1:0] in the DMA Conguration register have been set to 03h.
The bit allocation is given in Table 78.
[1]
The cycle duration indicates the internal clock cycle (33.3 ns/cycle).
