Counter Interrupt and Retransmit
[17, 45, 53, 54, 55, 56]
Notes:
53.CE
= OE = BE0 – BE3 = LOW; CE
1
= R/W = CNTRST = MRST = HIGH.
54.CNTINT is always driven.
55.CNTINT goes LOW when the unmasked portion of the address counter is incremented to the maximum value.
56.The mask register assumed to have the value of 3FFFFh.
