7.30.1
Reset
Reset has four sources on the LPC17xx: the RESET pin, the Watchdog reset, power-on
reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a Schmitt
trigger input pin. Assertion of chip Reset by any source, once the operating voltage attains
a usable level, causes the RSTOUT pin to go LOW and starts the wake-up timer (see
description in
Section 7.29.4
). The wake-up timer ensures that reset remains asserted
until the external Reset is de-asserted, the oscillator is running, a fixed number of clocks
have passed, and the flash controller has completed its initialization. Once reset is
de-asserted, or, in case of a BOD-triggered reset, once the voltage rises above the BOD
threshold, the RSTOUT pin goes HIGH.
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.
