Precautions for operation
Contents: In the case of a cascade edge trigger, the low level width (TILIH) of a slave INT signal
may be less than the low level width (TJLJH:100 ns min.) of a master IR input signal.
This occurs when an interruption request with high order priority is provided to the
slave unit before the INTA cycle ends. Fig.1 shows a system configuration, Fig.2 a bug
operation timing chart, and Fig.3 a normal operation timing chart. TILIH is not
specified.
