What is required to tie a digital output of one CPU(Superpro)Master to a digital I/O of another CPU(LPC1114)Slave. One is output the other is input. Need a simple signaling process from one cpu to the other. Can they be directly wired?

Yes the outputs of one CPU can be connected directly to another CPU. Both the 1756 and 1114 are 3V swing parts, and a 5V tolerant and compatible.
