LPC812 SPI1 Master Clock and Chip Select Missing

Using the following code to configure my SPI Master, I expect to see a 100 Kbs clock on P0_9, my sent signal on P0_15, and my chip select on P0_8.

        regVal = LPC_SWM->PINASSIGN4 & ~( 0xFFUL<<24 );
        LPC_SWM->PINASSIGN4 = regVal | ( 0x9<<24 );        //9 SCK
regVal = LPC_SWM->PIN  ASSIGN5 & ~( 0xFF<<0 );
LPC_SWM->PINASSIGN5 = regVal | ( 0xF<<0 );//15 MOSI
regVal = LPC_SWM->PINASSIGN5 & ~( 0xFF<<8 );
LPC_SWM->PINASSIGN5 = regVal | ( 0x11<<8 );//17 MISO
regVal = LPC_SWM->PINASSIGN5 & ~( 0xFF<<16 );
LPC_SWM->PINASSIGN5 = regVal | ( 0x8<<16 );//8 SSEL

        SPI_Init(LPC_SPI1, 0x7D, CFG_MASTER, DLY_PREDELAY(0)|DLY_POSTDELAY(0)|DLY_FRAMEDELAY(0)|DLY_INTERDELAY(0));

        message = (uint8_t *) TestSignal;
mSize = 2*sizeof(TestSignal) / sizeof(TestSignal[0]);

        SPI_Send( LPC_SPI1, CS_USED, message, mSize);

Probing each of these three pins, I see my test signal on pin P0_15 as expected, and the bit width is 10 microseconds as expected, corresponding to a clock period of 10 microseconds and a clock rate of 100 Kbs. However, I don't see a clock on P0_9 or the chip select on P0_8.

Any ideas what the problem could be? It should be noted that I am using SPI0 as a Slave and successfully receiving a signal from a master on pins 12, 13, and 14 before sending my master signal here.

Thanks!

If you are using the LPC812 dev kit, you will need to remove the jumpers from SJ2 and SJ3, pins 1-2 (removing the PIO_8/9 connections to the oscillator).  Then solder SJ2 and SJ3 jumper pins 2-3.  This then requires that you use the internal RC oscillator.  Now the dev kit pins will now be connected to PIO_8 and PIO_9.  See LPCExpresso LPC800 Rev B Schematic for details.

Pins 2 and 3 are the pins used to debug, so that is what froze up the board, by tying PIO0_1 (ISP_EN) to ground on power up, I was able to fix the error. Due to a lack of suitable pins, I have removed LED resistors from the board in order to use pins 16 and 17.

It would seem that pins 8 and 9 are not actually suitable for IO, though they claim to be. By switching to pins 2 and 3, I have remedied this problem, though now LPCXpresso says it cannot connect to the target. Documentation of the error does not seem to exist:
