90 / 129 page  WM8912 Production Data w PD, Rev 4.1, February 2013 90 POWER-ON RESET The WM8912 includes an internal Power-On-Reset (POR) circuit, which is used to reset the digital logic into a default state after power up. The POR circuit is powered from AVDD and monitors DCVDD. The internal POR ¯¯¯ signal is asserted low when AVDD and DCVDD are below minimum thresholds. The specific behaviour of the circuit will vary, depending on the relative timing of the supply voltages. Typical scenarios are illustrated in Figure 54 and Figure 55.
