[sdiy] PICs sharing pins and clock

[fmg]

To the pics gurus,

Is this possible?  I mean, can two (or more) PICs work together, one
with one of its pins working as output and connected to a second one
configured as input, both sharing a common external clock?

Example (for better clarity): pin RB0 (from PIC #1) as output and directly
connected to pin RA0 (from PIC #2) as input...

instruc.
 cycle       pic #1                        pic #2
------------------------------------------------------      (-x- = don't care)
  Tn           -x-                           -x-
 Tn+1      incf   portB,1   -------->   btfsc   portA,0
 Tn+2          -x-                      goto XX
 Tn+3          -x-                      goto YY

...will pic #2 go to XX if RB0 from pic #1 changes from 0x00 to 0x01 ?

The 16f84a's datasheet is a bit confusing (or I'm not interpreting it
correctly). I'm also not sure if this is the correct place to ask (even
if this is for a synth project)

Any light would be appreciated, TIA
