This article is marked for rewrite/restructuring in proper wiki format.
You can help PS3 Developer wiki by editing it.

JSD-001 motherboard

All the components listed are controlled by Syscon and connected to it by a pin/trace either directlly or indirectlly, the traces are hidden in internal layers of the motherboard

By looking at the first syscon model used by the PS3 CXR713120-201GB where we know the names of the pin signals it seems these syscon control lines for voltage regulators could be the syscon pins named SW_x or SW_x_x (switches, used as a generic name for slave components that only has 2 states)
