I1U
This internally pulled-up signal is used to configure this device
as a Master or a Slave. When this pin is grounded, this device
is configured as a Master. When the pin is open, this device is
configured as a Slave. The pin setting should remain the same
from Power-on to Power-down.
IORD#

F1
II2Z
This is an I/O Read strobe generated by the host. This signal
gates I/O data onto the bus from the chip.
IOWR#
