Boot Mode Select Jumpers (JP2–1)
The
JP1
and
JP2
jumpers determine the boot mode of the processor.
Table 3-4 shows the available boot mode settings. By default, the proces-
sor boots from the on-board Flash memory.
Core Voltage Source Select Jumper (JP3)
The core voltage of the processor can be derived from either the proces-
sor’s internal voltage regulator or from a fixed 1.4V external regulator. It
is necessary to use the 1.4V external regulator when the processor runs at
speeds greater than 600 MHz.
Table 3-5 summarizes the functionality of
the Core Voltage Source Select Jumper,
JP3
.
