I was hoping to find a generic '51 POST routine in the code library, but don't see anything. Anyone care to share? :)

How extensive a POST test do you normally run? Do today's micros fail often enough to make the effort and time required for a good POST worthwhile?

Here's the sequence I'm thinking of using. Any feedback is appreciated. "Check" means "verify proper operation of".

1. Check ALU using only accumulator and immediate constants
2. Check the active register set
3. Check direct, indirect, and indexed addressing
4. Perform a checksum on program memory
5. Perform a RAM test
6. Check the other register sets
7. Check that timers will count
8. Check that interrupts
9. Check SFRs as much as possible
10. Check any on-chip peripherals
11. Check external peripherals
