Production Data
The POR circuit requires that the DVDD is applied before the AVDD. The active low reset signal
NPOR will be asserted low until VMID rises to 1.2V. When this threshold has been reached, then
the NPOR is released and the digital interface has been reset. This is illustrated in the diagram
shown in Figure 5.
