1. Overview
The Cypress USB Development System is a powerful tool to assist development of user hardware and firmware
with emulated Cypress USB ICs. In the full development system environment (Figure 1), a PC-based interface
facilitates debugging through break-traps, single stepping, and display/modification of registers and data RAM. In
this mode, firmware can be implemented in on-board EPROM, or downloaded to program RAM. The RAM option
provides a quick and easy method for testing firmware revisions.
