SDO:
In serial host mode, the SDO data is output on this pin. If a
serial write is in progress this pin is in high impedance. During a
read SDO is high impedance when the SDI is in command/
address mode. If CLKE is low, SDO is output on the rising edge of
SCLK, if CLKE is high on the falling edge.
RDY:
A low on this pin reports to the host that the cycle is not
complete and wait states must be inserted. A high means the
cycle is complete.
ACKB:
In Motorola parallel mode, a low on this pin indicates that
the read data is available for the host or that the written data cycle
is complete.
RIMPOFF:
In hardware mode when this pin is high, all the RTIP
and RING pins have internal impedance switched off.

Active-Low Interrupt Bar.
This interrupt signal is driven low when
an event is detected on any of the enabled interrupt sources in any
of the register banks. When there are no active and enabled
interrupt sources, the pin can be programmed to either drive high
or not drive high. The reset default is to not drive high when there
are no active enabled interrupt sources. All interrupt sources are
disabled after a software reset and they must be programmed to
be enabled.

D[7:0]:
In nonmultiplexed host mode, these pins are the
bidirectional data bus.
AD[7:0]:
In multiplexed host mode, these pins are the bidirectional
address/data bus. Note that AD7 and AD6 do not carry address
information, and in serial host mode AD6–AD0 should be
grounded.
BSWP:
In serial host mode, this pin defines the serial data position
to be LSB first when low and MSB first when high.
LP[8:1]
In hardware mode, these pins set the loopback modes for
the corresponding LIU as follows:
Low
Remote Loopback

No Loopback
High
Analog Loopback
Note: When left unconnected and in hardware mode, do not route
signals with fast transitions near LP1–LP8. This practice minimizes
capacitive coupling.
