17.4
This section describes the functional behavior of the USB module. It documents data packet processing
for endpoint 0 and data endpoints, USB suspend and resume states, SOF token processing, reset conditions
and interrupts.

following sections. The module involves several major blocks — USB transceiver (XCVR), USB serial
interface engine (SIE), a 3.3 V regulator (VREG), endpoint buffer manager, shared RAM arbitration, USB
RAM and the SkyBlue gasket.
17.4.1.1
The SIE is composed of two major functions: TX Logic and RX Logic. These major functions are
described below in more detail. The TX and RX logic are connected by a USB protocol engine which
manages packet flow to and from the USB module. The SIE is connected to the rest of the system via

is the block diagram. The module’s sub-blocks and external signals are described in the
USB Serial Interface Engine (SIE)
Endpoint Stall — When set, this bit indicates that the endpoint is stalled. This bit has priority over all other
control bits in the endpoint control register, but is only valid if EPTXEN=1 or EPRXEN=1. Any access to this
endpoint will cause the USB module to return a STALL handshake. Once an endpoint is stalled it requires
intervention from the host controller.
0 Endpoint n is not stalled
1 Endpoint n is stalled
Endpoint Handshake — This bit determines if the endpoint will perform handshaking during a transaction
to the endpoint. This bit will generally be set unless the endpoint is isochronous.
0 No handshaking performed during a transaction to this endpoint (usually for isochronous endpoints)
1 Handshaking performed during a transaction to this endpoint
