#26182 - RE: Operating 2nd 8051 from 1st8051 port pin |
rams,
Erik's suggestion is a very good one. Using POWER DOWN your master '51 only has to RESET the slave '51 which is easily done with just a port pin. POWER DOWN is the battery solution. If you use IDLE Mode instead on POWER DOWN you get some additional procedural control as you can have your slave '51 sitting (dozing) at a post initialization code location waiting for an interrupt. regards, p |
