Jumpers are provided that allow for the 3.3V, 1.8V, and 1.5V supplies to be separated from the MCF52277.
The intention of these jumpers is to connect a current meter to measure the power consumed by the
MCF52277 processor.

The MCF52277 has three boot options:
The boot mode is determined by the BOOTMOD[1:0] inputs into the MCF52277. The mode switches
(SW5[2:1]) control the BOOTMOD[1:0] inputs to the MCF52277.
When booting from FlexBus with overrides from the data bus, the SW3 and SW4 settings control the state
of FB_AD[7:0] during reset (while /RSTOUT is asserted). The following table describes the override
settings.
