Freescale Semiconductor 4-9
Note: ETH_TXCLK and ETH_RXCLK (J16 pins 12 and 16) cannot be
disconnected from the ethernet transceiver so whatever alternate function uses
these pins on header J16 should expect the added capacitive load of the ethernet
transceiver.
Note: R67 must be installed to get the TIMER_3 function to work on pin 3 of J17.
Note: R66 must be installed to get the TIMER_2 function to work on pin 2 of J17.
