External Clock Disable Jumper (P37)
The EZ-KIT Lite provides a 27 MHz clock, which can be used as a trans-
mit clock for all of the interfaces as illustrated in
Figure 2-1 on page 2-2 .
When the 27 MHz clock is not being used, remove the jumper to prevent
the
TX_CLK
signal from being driven. For information about other transmit
clock sources, see “Clock Routing Switch (SW2)” on page 2-5 .
