Cypress calls this chip a 'low-speed USB Peripheral Controller' but in aTV it has nothing to do with the external USB port.
It is an 8-bit microcontroller with 8K of FLASH and 256 bytes of RAM, also a possible watch-dog timer for the system.
Its various GPIOs go to the header that the front baby-board connects to.
