MPC8272 Clock Mode Settings (SW8)
Switch SW8 determines the clock settings for the MPC8272 processor. When a switch is in the ON position, its
related signal is deasserted to 0. When the switch is in the OFF position, its related signal is asserted to 1. For
details, refer to the MPC8272 PowerQUICC II™ Family Reference Manual. The default factory settings for the
MSC711xADS board are switches 1, 4, 6 = OFF and all other switches are ON.
• Switches 1–3 set
MODCK[1–3]
, respectively.
• Switches 4–7 set
MODCKH[0–3]
, respectively.
• Switch 8 sets the PCIMODCK bit.

Main Power Switch (SW9)
Switch 9 is the main power ON–OFF switch. Toggling the switch turns the main power ON (down) or OFF (up).
2.4.8
MSC711x Ethernet PHY MII/RMII Mode (JP1)
JP1 selects the connection mode of the Ethernet PHY connected to the MSC711x. The mode must be selected
before power is turned on.
• In the MII (1-2) position, the PHY is in MII mode (factory default).
• In the RMII (2-3) position, the PHY is in RMII mode.
