ST10R172L - ELECTRICAL CHARACTERISTICS
1
This is the last chance for BREQ to trigger the regain-sequence indicated.
Even if BREQ is activated earlier, the regain-sequence is initiated by HOLD going high.
Please note that HOLD may also be de-activated without the ST10R172L requesting the
bus.

The next ST10R172L driven bus cycle may start here.
