i m not getting sck clock from lpc2378 fpr spi

respected sir
this is my code

int main (void)
{
SYS_TargetResetInit();
PCONP |= (1 << 8);
/* by default, it's enabled already, for safety reason */
PINSEL0 |= 0xC0000000;
PINSEL1 |= 0x0000003C;

S0SPCCR = 0x8;

S0SPCR = 0x000;
}

void SYS_TargetResetInit(void)
{
SCS |= 0x20;
/* Enable main OSC */
while( !(SCS & 0x40) );
/* Wait until main OSC is usable */
CLKSRCSEL = 0x1;
/* select main OSC, 12MHz, as the PLL clock source */
PCLKSEL0 = 0x55555555;
/* PCLK is the same as CCLK */
PCLKSEL1 = 0x55555555;
SYS_GPIOResetInit();
}
