Notes:
40. CE
41. CNTINT is always driven.
42. CNTINT goes LOW when the unmasked portion of the address counter is incremented to the maximum value.
43. The mask register assumed to have the value of 1FFFFh.
44. Retransmit happens if the counter remains in increment mode after it wraps to initially loaded value.
