16.1. Endpoint Addressing
A total of eight endpoint pipes are available. The control endpoint (Endpoint0) always functions as a
bi-directional IN/OUT endpoint. The other endpoints are implemented as three pairs of IN/OUT endpoint
pipes:
16.2. USB Transceiver
The USB Transceiver is configured via the USB0XCN register shown in SFR Definition 16.1. This configu-
ration includes Transceiver enable/disable, pull-up resistor enable/disable, and device speed selection
(Full or Low Speed). When bit SPEED = ‘1’, USB0 operates as a Full Speed USB function, and the on-chip
pull-up resistor (if enabled) appears on the D+ pin. When bit SPEED = ‘0’, USB0 operates as a Low Speed
USB function, and the on-chip pull-up resistor (if enabled) appears on the D- pin. Bits4-0 of register
USB0XCN can be used for Transceiver testing as described in SFR Definition 16.1. The pull-up resistor is
enabled only when VBUS is present (see
VBUS detection).
Important Note: The USB clock should be active before the Transceiver is enabled.
