5.1 Power supplies
When the "mini module" is plugged onto the motherboard, power is supplied directly by the motherboard. In this
setup, the external power supply input available on the "mini module" should NOT be used.
When the SPC58XXADPT64S rev.B "mini module" is used as a stand-alone board, external power supplies must
be used (5.0 V, 3.3 V, 1.25 V).
The following jumpers are used to configure the power supply:
