Hi all:

         Form the bf537 ezkit lite schematic, I noticed that UART0 is composed of 4 pins : PF0,PF1,PG6,PG7; but PG6 and PG7 is also PPI_DATA_6 and PPI_DATA_7 .

          My question is:  if i use uclinux on 537 , then  UART0 will be the terminal for the OS , also PG6 and PG7 is used as the terminal pins . Does it means that i can't use PPI at the same time??  How to fix this ?  thanks

the schematics show how two of the pins are multiplexed and not hooked up by default
