How can i reset LPC1114 from within the firmware?
The user manual did not elaborate on the sw reset?

"
Reset has four sources on the LPC111x/LPC11C1x: the RESET pin, Watchdog Reset,
Power-On Reset (POR), and Brown Out Detect (BOD). In addition, there is a software reset."

Hi,

there is something in the user manual for lpc11xx on the pages 378-379.

#define NVIC_SYSRESETREQ            2         /*!< System Reset Request         */
#define NVIC_AIRCR_VECTKEY    (0x5FA << 16)   /*!< AIRCR Key for write access   */

static __INLINE void NVIC_SystemReset(void)
{
  SCB->AIRCR  = (NVIC_AIRCR_VECTKEY | (1<<NVIC_SYSRESETREQ));                          /* Keep priority group unchanged */
  asm("DSB");
  while(1);                                                                            /* wait until reset */
}

Hope that help

Just use NVIC_SystemReset() :)

It's part of CMSIS and defined in core_cm0.h.
