Why is the reset vector address 0x1FF?

ORG 0x1FF

Thanks!

By design.
The PC is reset to all '1's on reset.
The data sheet has all of this information in it.

Thank you Susan

Good answer

Have another Baseline PIC question.

On the 10F200 datasheet there are the 202 204 and 206 too.

While they do add memory.

They also add a comparator.

Why are comparators important?

Thanks!

They are not if you don't want to use them.
However if you are (lets say) wanting to build a monitor for a battery and to know then it falls below some preset value, then the comparator will be useful for that. Basically it is used to compare two voltages and tells when one is above the other. What you use that information for is up to you.
