Note 1: Writing/Reading operation for the control register is performed during overlapping IOCS and (LWR or RD).
Limits of IOCS,LWR and RD are prescribed by the input signal of last change to "L" in starting access,
and by the input signal of first change to "H" in ending access.
TIMING DIAGRAM
(1) Write to control register ( RD = "H" )
Without WAIT
Data input is established
Address is established
(2) Read from control register (LWR= "H" )
Data output is established
Address is established
