USB Device
The CY7C637xx supports one USB Device Address with three endpoints: EP0, EP1, and EP2.
14.1
The USB Device Address Register contains a 7-bit USB address and one bit to enable USB communication. This register is
cleared during a reset, setting the USB device address to zero and marking this address as disabled.
Figure 14-1
shows the
format of the USB Address Register.
USB Address Register
In either USB or PS/2 mode, this register is cleared by both hardware resets and the USB bus reset. See Section 21.3 for more
information on the USB Bus Reset - PS/2 interrupt.
Bit 7: Device Address Enable
This bit must be enabled by firmware before the serial interface engine (SIE) will respond to USB traffic at the address specified
in Bit [6:0].
1 = Enable USB device address.
0 = Disable USB device address.
Bit [6:0]: Device Address Bit [6:0]
These bits must be set by firmware during the USB enumeration process (i.e., SetAddress) to the non-zero address assigned
by the USB host.
14.2
All USB devices are required to have an endpoint number 0 (EP0) that is used to initialize and control the USB device. EP0
provides access to the device configuration information and allows generic USB status and control accesses. EP0 is bidirectional
as the device can both receive and transmit data. EP0 uses an 8-byte FIFO at SRAM locations 0xF8-0xFF, as shown in Section
8.2.
The EP0 endpoint mode register uses the format shown in
Figure 14-2
.

For PS/2 operation, the D+/D– Forcing Bit [2:0] = 111b mode must be set initially (one time only) before using the other PS/2 force modes.
