Hi to all engineers.
I  would like to know more about my 8 questions

1. when you enable pull-up resisters are they really resisters if yes
what value are they like 10k or some thing.
2. in  short form card 16c62a when you see brawn out protection  YES  is
this means it has this brawn out
protection built in it you can enable it or disable it.
3. what it the idea of pic16c62a  RA4 to be always open collector when
you use it as output.
4. since pic has power on reset what is the idea of having reset pin
that almost always pulled high.
5. when you program pics and you got error massage is this means pic was
defective or I did some thing wrong.
6. when you use JW parts there is no frequency number on it is this
means it is good up 20 MHZ.
7. when you use serial programing how many pics can be programed at the
same times.
8. when you do serial number programing using PROMATE can you read the
serial number after code protection on if not
what is the idea to program serial number if you can not read it
