Are you trying to force the CLK input of a PIC16C/F54 when it's set to RC mode?
This doesn't work, or, if it does, you are just lucky due to the series resistance and drive level of your source clock.  (I'm not saying you cant do it...)
To guarantee a functional clock feed to the PIC16F54 clk-in pin, you need to set it's config bits to XT or HS as if you were using a crystal.  Leave the clk-out unconnected, or use it to feed another device.

Nope :-)

I only had it in RC mode while using the RC Network.  Now I have an OSC on the board it's in XT mode.
Meh....
