An output can drive 16mA OK, but there is a limit on the maximum current any
particular port can sink or source in total.  PortB can source a maximum of
100mA.  8x16=128mA which would be out of spec.  It can however sink 150mA
which would  mean that the second PIC wouldn't be required in this case,
although I suspect it'll start getting warm....
