Anybody out there using the built in CRC engine in the LPC1788?

I thought this was pretty cool:

<code>
uint32_t CRC_32( uint8_t *Data, uint32_t Size )
   {
   uint32_t *temp = (uint32_t *)(Data);
  
   LPC_CRC->MODE = 0x36;
   LPC_CRC->SEED = 0xFFFFFFFF;
   while( Size-- != 0 )
      {
      LPC_CRC->WR_DATA_DWORD.DATA = *temp++;
      }
   return( LPC_CRC->SUM );
   }
</code>

Beats the heck out of building a look-up table  :-)
