Syscon Hardware
Syscon is the main power controller chip. It is responsible for powering up the various power systems and for configuring and initialising the CELL BE, RSX and South Bridge. 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.

Syscon UART
You can attach a 3.3v TTL cable (LV-TTL) to the UART on syscon. There is a simple plaintext protocol involved. This varies on different syscon models. Example:
<command>:<hash>
Where the hash is the sum of command bytes & 0xFF
you should terminate commands with \r\n, the syscon messages are only terminated with \n
Here are some of the commands/messages encountered:
Messages: Power applied (standby mode) OK 00000000:3A Power on # (PowerOn State):7F Power off (Hard shutdown) # (PowerOff State):DD After Fan test: # (PowerOff State) (Fatal):36 No text, invalid hash: NG F0000002:4D Commands: VER:ED OK 00000000 S1E 00 00 065D:A4 ERRLOG:CB OK 00000000:3A DATE:1E NG F0000003:4E
