The following table shows how the control bits are encoded for this register.
Table 17-2. Control Bit Definition for Upstream Port
18.0
The compound device (Device Address A) includes three endpoints: EPA0, EPA1, and EPA2. End Point 0 (EPA0) allows the USB
host to recognize, set up, and control the device. In particular, EPA0 is used to receive and transmit control (including set-up)
packets.
18.1
The USB Controller provides two USB Device Address Registers (A and B). Upon reset and under default conditions, Device A
has three endpoints while Device B has two endpoints. The USB Device Address Register contents are cleared during a reset,
setting the USB device addresses to zero and marking these addresses as disabled. Figure 18-1 shows the format of the USB
Address Register.
Bit 7 (Device Address Enable) in the USB Device Address Register must be set by firmware before the serial interface engine
(SIE) will respond to USB traffic to these addresses. The Device Address in bits [6:0] are set during the USB enumeration process
to a non-zero address assigned by the USB host.
18.2
The CY7C66xxx controller supports up to two addresses and five endpoints for communication with the host. The configuration
of these endpoints, and associated FIFOs, is controlled by bits [7,6] of the of the USB Status and Control Register (0x1F) Bit 7
controls the size of the endpoints and bit 6 controls the number of addresses. These configuration options are detailed in Table
18-1 .
Table 18-1. Memory Allocation for Endpoints
All USB devices are required to have a control endpoint 0 (EPA0 and EPB0) that is used to initialize and control each USB address.
Endpoint 0 provides access to the device configuration information and allows generic USB status and control accesses. Endpoint
0 is bidirectional as the USB controller can both receive and transmit data.
The endpoint mode registers are cleared during reset. The EPA0 and EPB0 endpoint mode registers use the format shown in
Figure 18-2 .
