LPC804

32-bit Arm Cortex-M0+ microcontroller

A LOW-going pulse as short as 50 ns resets the part.

When the internal Reset is removed, the processor begins executing at address 0, which

is initially the Reset vector mapped from the boot block. At that point, all of the processor

and peripheral registers have been initialized to predetermined values.

9.26.2 Brownout detection

The LPC804 includes one reset level and three interrupt levels for monitoring the voltage

on the VDD pin. If this voltage falls below one of the selected levels, the BOD asserts an

interrupt signal to the NVIC. This signal can be enabled for interrupt in the Interrupt

Enable Register in the NVIC to cause a CPU interrupt. Alternatively, software can monitor

the signal by reading a dedicated status register. One threshold level can be selected to

cause a forced reset of the chip.
