1) Does ADuC831 have an internal pull-down resistor connected to RESET pin? If
so what value (in kohms) is it. If no - should I use an external resistor?

2) Is Aduc 831 reset after power-on? Or do I have to use RC on RST pin to force
high state on RST pin to correctly reset the ADuC after power-on.

 

1) There is a weak internal pullup (about 10 kOhm nominal) : if you are worried
about glitches in a noisy environment we suggest you add a strong external
pullup- 1 Kohm should be fine.

2) Power on Reset is automatic.
