7.0 X-Bus Extension
2. Bear in mind the following system design hints for asynchronous X-Bus use:
3. Address multiplexing on XDT7-0 and the XSTB2-0 is designed for glueless interface with off-chip latch components. See

PIRQA-D
GND
If any of the functions multiplexed on XA18-12 (Game Port or Serial Port 2) are needed, use an external latch for these
signals.
Use the XRDY signal that is enabled upon reset. Either of the XIORD and XIOWR signals may be used. Set proper sys-
tem configuration before accessing a PC87570 or any I/O device with separate read and write signals for I/O and mem-
ory transactions.
The chip select signal should be used as a qualifier with the address when partial address decoding is in use for mul-
tiple device access control.
In read cycles, the system may drive the data until the read signal XRD is de-asserted to guarantee the proper
PC8739x sampling.
In write cycles, use either the falling or rising edge of the write control signal (XWR) to latch the data in the device.
