Readback State of Address Counter or Mask Register
[42, 43, 44, 45]
Notes:
42.CE
= OE = BE0 – BE1 = LOW; CE
= R/W = CNTRST = MRST = HIGH.
43.Address in output mode. Host must not be driving address bus after t
CKLZ
in next clock cycle.
44.Address in input mode. Host can drive address bus after t
.
45.An * is the internal value of the address counter (or the mask register depending on the CNT/MSK level) being Read out on the address lines.
