Each endpoint is controlled by an Endpoint Control
Register.
Descriptors (BD) for the following endpoints:
The user will be required to disable unused Endpoints
and directions using the Endpoint Control Registers.

Endpoint Registers
The
tion of the endpoint. The endpoint enable/direction control is defined as follows:
control bits in the Endpoint Enable register, but is only valid if EP_IN_EN=1 or EP_OUT_EN=1. Any access
to this endpoint will cause the USB to return a STALL handshake. The EP_STALL bit can be set or cleared
by the SIE. Refer to the USB 1.1 Specification, Sections 4.4.4 and 8.5.2 for more details on the STALL
protocol.
U-0
EP_STALL: When this bit is set it indicates that the endpoint is stalled. This bit has priority over all other

10.5.1.10 USB Endpoint Control Register (EPCn)
The Endpoint Control Register contains the endpoint
control bits for each of the 6 endpoints available on
USB for a decoded address. These four bits define the
control necessary for any one endpoint. Endpoint 0
(ENDP0) is associated with control pipe 0 which is
required by USB for all functions (IN, OUT, and
SETUP). Therefore, after a USB_RST interrupt has
been received, the microprocessor should set UEP0 to
contain 06h.
Note:
R/W-0
These registers are initialized in response
to a RESET from the host. The user
must
USB_CH9.ASM to configure the endpoints
as needed for the application.
