10.6.7
DMA Endpoint register (R/W: 0258h)
This 1 B register selects a USB endpoint FIFO as the source or destination for DMA
transfers. The bit allocation is given in
Table 133
.
[1]
The reserved bits should always be written with the reset value.
The DMA Endpoint register must not reference the endpoint that is indexed by the
Endpoint Index register (022Ch) at any time. Doing so would 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.
10.6.8
DMA Burst Counter register (R/W: 0264h)
The bit allocation of the register is given in
Table 135
.
[1]
The reserved bits should always be written with the reset value.
