Table 138. DMA Endpoint register (address 0258h) bit description
The DMA Endpoint register must not reference the endpoint that is indexed by the
Endpoint Index register (022Ch) 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 firmware must not
reference the same endpoint on the Endpoint Index register.
The bit allocation of the register is given in
