3.2 Surface mount links
The ARM710T header card has three surface mount links, LK1, LK2, and LK3, which
should not be moved for normal operation. Link LK1 sets the global bus enable, GBE,
to HIGH (A-C position, default) or LOW (B-C position). Links LK2 and LK3 are used
to control which grant and request signals (from the arbiter on the ARM development
board) are used by the processor. Figure 3-2 shows the default position of links LK1,
LK2 and LK3.
