NGW/NGW100 Reset circuitry

From AVRFreaks Wiki

Jump to: navigation, search

The Network Gateway (NGW) have two reset circuits. One reset circuit is used for the CPU and the board controller and one reset circuit is used for the Ethernet Physical circuits and the parallel flash chip.

Both reset nets are pulled low by the same reset switch button. The different rise times of the two delay networks ensure that the Flash exit the reset state before the CPU.
