Reset ID

Instead of using a watchdog to force a reset use the CMSIS call

static __INLINE void NVIC_SystemReset(void)

which will result in the Reset Source Identification Register setting SYSRESET bit.  This frees up the watchdog to be used as an actual watchdog.  Right now, if the watchdog times out, the system enters bootload mode, it does not reset

Thank you for the suggestion. For LPC177X/8X that is definitely a better method of resetting the MCU. The watchdog implementation was a carry over from the LPC175X/6X which did support the SYSRESET bit. We will get this change into a future release for the LPC177x8x
