Error using SPI module in P89V51RD2

Hi, I am trying to use P89V51RD2 controller for SPI module.

I have written

#include<intrins.h>

#include <P89V51Rx2.h>

sbit LE=P1^4;

sbit MOSI=P1^5;

sbit MISO=P1^6;

sbit clk=P1^7;

void main(void)

{

	TMOD=0x20;			//TIMER 1 MODE 2 AUTO RELOAD
	TH1=0xFD;			//9600 BAUD RATE @11.0592 mhZ

SCON=0x50;

// UART in Mode 1, 8Bit Data, 1Stop Bit, 1Start Bit

SPCTL= 0x51;

TR1= 1;

}

but I could not get anything on port pins MOSI or clk.

Please tell me What am I missing?
