After the receipt of a MON-8-command the IEC-Q will set the address/data bits and
generate a read or write pulse.
The address bits are latched, and the output is stable until a new dedicated
command is issued.
The initial value on the address lines after a software, hardware or power-on reset is

For every change at the input pin INT, the IEC-Q will transmit a C/I-channel code

The input condition of the pin INT is sampled every 4 IOM
indication must therefore be applied to pin "INT" for at least 4 IOM
