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 MON-8
command is issued.
The initial value on the address lines after a software, hardware or power-on reset is
(11B).
4.10.2
Interrupt
For every change at the input pin INT, the IEC-Q will transmit a C/I-channel code
(0110B), INT, in 4 successive IOM®-2-frames.
Note 60: Interpretation of the interrupt cause and resulting actions need to be
performed by the control unit.
The input condition of the pin INT is sampled every 4 IOM®-2-frames. An interrupt
indication must therefore be applied to pin "INT" for at least 4 IOM®-2-frames.
