Flexbus CS3 K63

I currently have an issue getting the Chip Select 3(CS3) Port C19 working with the flexbus on the K63 micro.

I already use CS0 and CS2 to access a PSRAM and LCD respectively.

I have setup the CS3 the same as the CS2 and I don't see the CS3 line change.

In the Manual it states that  CSCR[AA] bit must also be set, which I believe I have.

I have the following configuration.

PORTC->PCR[19] = PORT_PCR_MUX(5);                //CS_3

FB->CS[3].CSAR = 0x80000000

FB->CS[3].CSMR = FB_CSMR_V_MASK;   

FB->CS[3].CSCR = FB_CSCR_AA_MASK;

FB->CS[3].CSCR  |= (FB_CSCR_PS(2)|FB_CSCR_WS(0x0e));     

FB->CSPMCR = (FB_CSPMCR_GROUP4(1)|FB_CSPMCR_GROUP5(1));   

 

Has anyone else had issues getting the CS3 on flexbus working. 

Am I totally missing something?

 

Any Help greatly appreciated.
