11.9.1 Power requirements
11.9.2 Clocks
Once data has been received or sent, the endpoint buffer can be read or written. How this
is accomplished depends on the endpoint’s type and operating mode. The two operating
modes for each endpoint are Slave (CPU-controlled) mode, and DMA mode.
In Slave mode, the CPU transfers data between RAM and the endpoint buffer using the
Register Interface. See
this mode.
In DMA mode, the DMA transfers data between RAM and the endpoint buffer. See
Section 11.15 “DMA operation”
Table 186. USB external interface
This section describes the clocking and power management features of the USB Device
Controller.
The USB protocol insists on power management by the device. This becomes very critical
if the device draws power from the bus (bus-powered device). The following constraints
should be met by a bus-powered device:
