Notes
Notes:
1. QACK in a logical high state at the transition of HRESET from asserted to negated enables standard pre-charge mode in the
750GX.
QACK in a logical low state at the transition of HRESET from asserted to negated enables extended pre-charge mode in the
750GX.
2. QACK, in a logical low state at the transition of QREQ from asserted to negated, enables the 750GX processor to enter the soft
stop (Nap) state for proper JTAG emulator operation.
