Reset IC on BF548 EZ-Kit

Hi,

 

In BF-548 EVK, no pull-down resistor is used on nRESET pin of processor, instead a pull-up is used on nRESET output pin of ADM708SARZ, which is going to reset to BF548, 

 

1. What will be the state of processor till 3.3V is generated by regulator on-board, i think there should be a pull-down resistor on reset pin of processor.

2. Reset IC schematic is also incomplete, VCC pin is not shown in schematics which is being monitored for reset.

 

Thanks.
