Table 1 Power on/off Reset Timing  
At power on, when VDD and VMID have been established, PORB is released and the  
WM8725 has been reset.  
At power down, PORB is asserted low whenever VMID drops below the minimum threshold of  
Vpor_off.  
If VDD is removed at any time, the internal power-on reset circuit is powered down and PORB  
will follow VDD.
