Notes:

12.OE is asynchronously controlled; all other inputs (excluding MRST) are synchronous to the rising clock edge.

13.CNTLD = VIL, MKLD = VIH, CNTINC = x, and MRST = CNTRST = VIH.

14.The output is disabled (high-impedance state) by CE = VIH following the next rising edge of the clock.

15.Addresses do not have to be accessed sequentially. Note 13 indicates that address is constantly loaded on the rising edge of the CLK. Numbers are for reference only.

16.CE is internal signal. CE = VIL if CE0 = VIL and CE1 = VIH.
