Notes
30. OE is asynchronously controlled; all other inputs (excluding MRST and JTAG) are synchronous to the rising clock edge.
31. ADS = CNTEN = LOW, and MRST = CNTRST = CNT/MSK = HIGH.
32. The output is disabled (high-impedance state) by CE = V
IH
 following the next rising edge of the clock.
33. Addresses need not be accessed sequentially because ADS = CNTEN = V
IL
 with CNT/MSK = V
IH
 constantly loads the address on the rising edge of the CLK. 
Numbers are for reference only.
