Overview
1. The Dual-Bank function provides two banks for an endpoint. This feature is used for ping-pong mode.
USB Endpoint Description
Mnemonic
The USB Device Port (UDP) is compliant with the Universal Serial Bus (USB) V2.0 full-speed
device specification.
Each endpoint can be configured in one of several USB transfer types. It can be associated with
one or two banks of a dual-port RAM used to store the current data payload. If two banks are
used, one DPR bank is read or written by the processor, while the other is read or written by the
USB device peripheral. This feature is mandatory for isochronous endpoints. Thus the device
maintains the maximum bandwidth (1M bytes/s) by working with endpoints with two banks of
DPR.
Suspend and resume are automatically detected by the USB device, which notifies the proces-
sor by raising an interrupt. Depending on the product, an external signal can be used to send a
wake up to the USB host controller.
