Lpc2000

I'm using the Keil uVision IDE tool and the LPC2129. My question is 
about setting up single edge hardware PWMs. Someone previously 
posted the following code:

REG(PWM0_PR)=0x0000;  //no prescaler - one cpu clk is one PWM clk
REG(PWM0_MCR)=0x0002; //Reset timer counter register on match0
REG(PWM0_PCR)=0x7E00; //enable each individual PWM, single edge
REG(PWM0_TCR)=0x000A; //Reset TC counter

REG(PWM0_MR0)=0x0400; //set up the PWM period
REG(PWM0_LER)|=BIT0;  //Latch the value

REG(PWM0_MR1)=0x0050; //set up initial PWM duty cycle
REG(PWM0_LER)|=BIT1;  //latch the value

REG(PWM0_MR2)=0x0100; //set up initial PWM duty cycle
REG(PWM0_LER)|=BIT2;  //latch the value

REG(PWM0_MR3)=0x150;  //set up initial PWM duty cycle
REG(PWM0_LER)|=BIT3;  //latch the value

REG(PWM0_TCR)=0x0009; //set the TC coutner and enable all PWMs

I added "PINSEL0 = 0x0005800A;" to enable UART1 and PWM 1-3, however 
I'm unsure of what else is required to have an output of the initial 
PWM duty cycle. 

Thanks.
