K70 Flexbus Problem - Bus Faults

I have setup the Flexbus to read from a 16bit ADC. I am using AD0-AD15 and one chip select (CS1). I don't mind that it is multiplexed because I was thinking the RD line would just get the data at the correct part of the read cycle.


I am using Processor Expert.


I set the Flexbus up with a base address of ox60000000.


PE Automatically enables the clock to the FlexBus, or so it seems.


When I attempt to read with something like:


uint16Val = *((uint16 *)0x60000000)


uint32Val = *((uint32 *)0x60000000)


I get a bus fault. I can't figure out what I am doing wrong. Please Advise!!!
