I have been studying the
8032 microcontroller. It is mentioned that
8032 doesn't have internal ROM. Now there are few questions I have
Do we need an external ROM to execute programs necessarily? Can't we use the 256 byte internal RAM?
Suppose I am using the 8032 microcontroller with an external ROM
2732and also using a latch for storing the address (lower order) of port P0.(which may transfer address/data). Now after enabling EA and connecting the PSEN how does 8032 execute the program? What happens if I turn on the system ?(How does the program counter of 8032 microcontroller executes intructions? From which address of external memory the program should be read ?
