Syscon Hardware

General Information

Syscon is the main power controller chip. It is responsible for powering up the various power systems and for configuring and initialising the CELL, RSX and southbridge. It communicates with these devices via seperate SPI busses. There is external access by JTAG (Which appears to have been disabled after factory programming) and Serial.
