Relation of the timing of the BUSY signal and the *ACK signal

[Center – ACK]

[While receiving INIT signal]

Note: If the *Init signal does not have width of 10 to 15

µsec or more, it

cannot act as an Init signal. If it is lower, the *Init signal is ignored.

BUSY starts up when the *Init signal is perceived.
