Power-on and external reset  
Figure 4 shows power-on and reset timing of the CYW89820. After VBAT is applied and reset is inactive, the  
internal buck turns on, followed by the RF and Digital LDOs. Once the LDO outputs have stabilized, the PMU allows  
the digital core to come out of reset. As shown in the figure, external reset can be applied at any time subsequent  
to power up.
