Downloading code to CY7C67300 by uart

Question: Is it possible to download code to CY7C67300 by uart?

 

Answer:

After power up, the BIOS reserves a background task for the UART/USB via the uart_idle and the usb_idle tasks. These background tasks call the SCAN interrupt for the special signature word 0xC3B6 from the UART/USB. If found, the Signature Scan Opcodes and data are processed, allowing code and data to be moved into the CY16's RAM space and executed. For more information please refer to page 35 of 172 of the Bios User Manual, available on our website. http://www.cypress.com/?rID=14316
