LPC1549 to LPC1517

Team,

I am wondering if I move from using the LPC1549 (in dev board) to LPC1517 for production, do I have ot make any changes to the code? Even when I develop on the LPC1549, i am not using functions that are not available on LPC1517 and making sure the code size fits LPC1517

Also I see that by default on LPC1549 the clock is set to system clock instead of the external oscillator. If i need to change to external xtal (with 20MHz freq)Do i change the following code?

<<Code>>
//
//   <h> System Oscillator Control (SYSOSCCTRL)
//     <o.0>      BYPASS: System Oscillator Bypass Enable
//                     <i> If enabled then PLL input (sys_osc_clk) is fed
//                     <i> directly from XTALIN and XTALOUT pins.
//     <o.1>      FREQRANGE: System Oscillator Frequency Range
//                     <i> Determines frequency range for Low-power oscillator.
//                   <0=> 1 - 20 MHz
//                   <1=> 15 - 25 MHz
//   </h>
#define SYSOSCCTRL_Val        0x00000001              // Reset value: 0x000
//
<</Code>>

Thanks a bunch for your help
