Several important registers that make significant influence on generated signals are at undefined state after powerup, namely, FANOUT register (187) and Spread Spectrum Parameters register (149). If, occasionally, fanout or spread spectrum will be enabled at powerup, the device will output unexpected signals.
These registers must be initialized explicitly.
