Read the user manual.
Chapter 32 tells you all about the flash, layout of the flash and different ways of programming the flash.
This chapter also gives you the exact interface to the flash programming tools that are part of the boot ROM.
You could also have a look at the blockdev_flash.c file that is in the usb_bootloader (part of the RDB1768cmsis2.zip package that is installed with the LPCXpresso 4.0.5 tools) there you will see an example of how the flash is programmed.
