In one of the examples (autoisp) for the lpc1343 its says:

/* Go to sleep to save power between SYSTICK interrupts */
    __WFI();

what is WFI?  Can I use this single statement to save power or must I dig out a more complex solution or preset something?
Please and thank you.

__WFI(); is a function in C, and define an instruction that has the same name in assembler (WFI: Wait For Interrupt).

In the datasheet has more information.

There is an elaborate example "pmc" in "LPC11xx_SampleSoftware.101".
