16F819 serin

[markedwards]

I have tried T9600, N9600, OT9600, ON9600.

I tested the B1 input energizing a digital output and that works.
I tried serin on B4 and it doesn't seem to work either.

I'm stuck

looks like a faulty one since RB4 is multiplexed with the MSSP and it's disable at start-up...

On wich pin the other PIC send the data???

RA.4??? If so is there any pull-up resistor attach to??

any on PORTA??? if so, is all analog stuff are disable???
