Does LPC4357 support Burst Read and Single Write Mode while accessing SDRAM?

Hello guys!
My SDRAM driver work normally in Burst Read and Burst Write Mode except the condition below:

                px = (UINT_SDRAM*)(SDRAM_ADDR_BASE);
Uart1SendString("Test Running");
for(i=0x1000000;i>0;i-=1)
{
k=k%100;
*px = (k) ;
px+=2;   //if px+=1; SDRAM works well
                                     //if px+=2 or 3 or 4 or other number bigger than 1 Data couldn't be writen to SDRAM
++k;
}

Here is My Mode Register setting(Burst Read and Burst Write Mode):
temp = *((volatile uint32_t *)(SDRAM_ADDR_BASE | (0x32<<13))); /* 4 burst, 3 CAS latency */

I've been tried to modify the value of Mode Register(0x32-->0x232, which changes sdram's writen mode from burst o single according to the datasheet).But it helps nothing.

I wonder if LPC4357 support Burst Read and Single Write Mode while accessing SDRAM.Does anyone know about this?

Thanks! And sorry for my poor English.
