USB Control Endpoint Registers
200h
CNTCTL
Control Endpoint Control/Status
Contains control and status bits for the Control
endpoint (endpoint 0).
202h
CNTSIZ
Control Endpoint Receive Packet Size
Shows the size of the packet present in the
Control endpoint’s FIFO.
206h
CNTDAT
Control Endpoint Data Port
Used to read from or write to the Control
endpoint’s FIFO. The FIFO address pointer is
advanced on each access.
208h
CNTRPK
Control Endpoint Receive Data Port
Peek
Used to read the current value in the Control
endpoint’s FIFO without advancing the FIFO
pointer.
20Ah
CNTDEF1
Control Endpoint Definition 1
Shows the control endpoint’s definition:
endpoint number, configuration, interface,
alternate setting, direction, and type. These
parameters are fixed for the control endpoint.
20Ch
CNTDEF2
Control Endpoint Definition 2
Shows the control endpoint’s FIFO size and
maximum packet size. These parameters are
fixed for the control endpoint.
USB Interrupt Endpoint Registers
210h
IEPCTL
Interrupt Endpoint Control/Status
Contains control and status bits for the
Interrupt endpoint.
216h
IEPDAT
Interrupt Endpoint Data Port
Used to write to the interrupt endpoint’s FIFO.
The FIFO address pointer is advanced on each
access.
21Ah
IEPDEF1
Interrupt Endpoint Definition 1
Used to set the interrupt endpoint’s definition:
endpoint number, configuration, interface,
alternate setting. The interrupt endpoint’s
direction (IN) and type (interrupt) are fixed.
21Ch
IEPDEF2
Interrupt Endpoint Definition 2
Used to set the interrupt endpoint’s FIFO size
(fixed for the interrupt endpoint) and maximum
packet size.
USB Data Endpoint A Registers
220h
AEPCTL
A Endpoint Control/Status
Contains control, status, and error bits for the
endpoint.
222h
AEPSIZ
A Endpoint Received Packet Size
Shows the size of the packet present in the
endpoint’s FIFO.
224h
AEPBUFS
A Endpoint Buffer Status
Shows the number of bytes present in the
endpoint’s FIFO.
226h
AEPDAT
A Endpoint Data Port
Used to read from or write to the endpoint’s
FIFO. The FIFO address pointer is advanced
on each access.
228h
ARCVPK
A Endpoint Receive Data Port Peek
Used to read the current value in the endpoint’s
FIFO without advancing the FIFO pointer.
22Ah
AEPDEF1
A Endpoint Definition 1
Used to set the endpoint’s definition: endpoint
number, configuration, interface, alternate
setting, direction, and type.
