5-158 Bus Interface
AMD-K5 Processor Technical Reference Manual 18524C/0—Nov1996
For an AHOLD inquire cycle to be recognized, AHOLD must
have been asserted continuously for two clocks at the time
EADS is asserted. AHOLD and BOFF can be asserted in con-
junction with each other without interfering with EADS recog-
nition, as long as the sampling criteria for at least one of the
signals (AHOLD or BOFF) is met.
