2.18.4.10 USB DMAx Request Registers
2.18.4.11 USB Endpoint Enable Register
The USB DMAx Request Registers, shown in Figure 1.41 and Figure 1.42, are used to select which USB End-
point x FIFO read/write requests are selected as the DMAC channel 0 or channel 1 request source. The USB
DMA0 (DMA1) Request Register should have only one bit set at any given time. When multiple bits are set,
no request is selected.
The USB Endpoint Enable Register, shown in Figure 1.43, is used to enable/disable an individual endpoint.
Endpoint 0 is always enabled and cannot be disabled by firmware. All endpoints are enabled after reset.
