Readback State of Address Counter or Mask Register
[34, 35, 36, 37]
Notes:
34. CE
= OE = B0 – B3 = LOW; CE
= R/W = CNTRST = MRST = HIGH.
35. Address in output mode. Host must not be driving address bus after t
CKLZ
in next clock cycle.
36. Address in input mode. Host can drive address bus after t
.
37. 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.
