Preliminary Information AMD-K6™-2E+ Embedded Processor Data Sheet 23542A/0-September 2000 processor latches the edge-sensitive signals (INIT, FLUSH#, NMI, and SMI#), but otherwise does not exit the Stop Grant state to service the interrupt. When the processor returns to the Normal state due to sampling STPCLK# negated, any pending interrupts are recognized after returning to the Normal state. To ensure their recognition, all of the normal requirements for these input signals apply within the Stop Grant state. If RESET is sampled asserted in the Stop Grant state, the processor immediately returns to the Normal state and the reset process begins. 14.4 Stop Grant Inquire State Enter Stop Grant Inquire State The Stop Grant Inquire state is entered from the Stop Grant state or the Halt state when EADS# is sampled asserted during an inquire cycle initiated by the system logic. The AMD-K6-2E+ processor responds to an inquire cycle in the same manner as in the Normal state by driving HIT# and HITM#. If the inquire cycle hits a modified cache line, the processor performs a writeback cycle. Exit Stop Grant Inquire State Following the completion of any writeback, the processor returns to the state from which it entered the Stop Grant Inquire state. 280 Clock Control Chapter 14
