USB Endpoint Enable Register
USB DMAx Request Register (x = 0 to 3)
The USB Endpoint Enable Register, shown in Figure 1.53, is used to enable/disable an individual endpoint. EP0 is
always enabled and cannot be disabled by firmware. All endpoints are disabled after reset.
The USB DMAx Request Register, shown in Figure 1.54, selects which USB EPx FIFO read/write requests are used as
the DMAC channels 0 to 3 request source. Each USB DMAx Request Registers should have only one bit set at any given
time. When multiple bits are set, no request is selected.
