PLL Configuration

Hi

We are using LPC2366 controller

When we configure the Internal RC oscillator(4 MHZ) for the PLL as shown below

Main OScillator = disabled
PLL source = Internal RC oscillator(4 MHZ )
M = 35
N = 1
so FCCO = 280MHZ

and Cpu clock frequency is 56MHZ
When we enter into the debug mode
the execution is not coming out of the PLL Lock sequence

; Wait until PLL Locked
PLL_Loop LDR R3, [R0, #PLLSTAT_OFS] ANDS R3, R3, #PLLSTAT_PLOCK BEQ PLL_Loop

Could you please guide us
