Note:
A = Earliest time at which NMI or SMI is recognized.
A RESET or SRESET brings the CPU from the Stop
Grant state to the Normal state. The CPU recognizes
the inputs required for cache invalidations (HOLD,
AHOLD, BOFF, and EADS) as explained later. The CPU
does not recognize any other inputs while in the Stop
Grant state. Input signals to the
CPU are not recognized
until 1 clock after STPCLK is deasserted (see Figure 21).
While in the Stop Grant state, the CPU does not recog-
nize transitions on the interrupt signals (SMI, NMI, and
INTR). Driving an active edge on either SMI or NMI does
not guarantee recognition and service of the interrupt
request following exit from the Stop Grant state. How-
ever, if one of the interrupt signals (SMI, NMI, or INTR)
is driven active while the CPU is in the Stop Grant state,
and held active for at least one CLK after STPCLK is
deasserted, the corresponding interrupt will be serviced.
