Read the full replyI have spent some time trying to work out what an 8032 does on cold start i.e. are there cold/warm start vectors etc etc? The data sheets from Philips/Temic etc don't seem to indicate. Or do they simply start executing at 0000h?
(I've been asked to look into an 8032-based board that isn't playing as it should. Reset doesn't seem to get it starting up properly.)
Thanks for any guidance.

So at initial power-on or after a RESET, 0->PC?

According to my 1985 Intel Microcontroller Handbook, the MCS-51 family has the following interrupt sources and service vectors:
Table 3. 8051 Interrupt Sources and Service Vectors
Interrupt Source Service Routine Start Address
---------------------------------------------------- (Reset) 0000H External 0 0003H Timer/Counter 0 000BH External 1 0013H Timer/Counter 1 001BH Serial Port 0023H
External 0/1 would correspond to pins INT0/1.
The 8032 appears to be identical to the 8031 except that it has twice as much RAM (256 bytes versus 128) and 3 timer/counters instead of 2.
The manual states that "each source has a particular program memory address associated with it (Table 3), starting at 0003H (as in the
8048) and continuing at 8-byte intervals".- Franc Zabkar
