USB INTERFACE (Cont’d)
USB Endpoint RAM Buffers
There are five bidirectional Endpoints including
one control Endpoint 0. Endpoint 1 and Endpoint 2
are counted as 4 bulk or interrupt Endpoints (two
IN and two OUT).
Endpoint 0 and Endpoint 1 are both 2 x 16 bytes in
size. Endpoint 2 is 2 x 64 bytes in size and can be
configured to physically target different USB Data
Buffer areas depending on the MOD[1:0] bits in

Figure
The USB Data Buffer operates as a double buffer;
while one 512-byte block is being read/written by
the DTC, the USB interface reads/writes the other
512-byte block.
The management of the data transfer is performed
in upload and download mode (2 x 512 byte buff-
ers for Endpoint 2) by the USB Data Buffer Manag-
er.
