8.5.3 Timing in the Asynchronous Intel Mode (X86 Mode) :

In 80X86 operation, SPC3 acts like memory with ready logic. The access times depend on the type of accesses.

The request for an access to SPC3 is generated from the negative edge of the read signal or the positive edge of the write signal.

SPC3 generates the Ready signal synchronously to the fed in pulse. The Ready signal is reset when the read signal or write signal is deactivated. The data bus is switched to the Tristate with XRD = 1.
