I/O
Ready Output (Data Transfer Acknowledge)
Host Mode (Parallel Microprocessor)
If Pin SER_PAR is pulled "Low", this output pin from the microprocessor block is used
to inform the local
μ
P that the Read or Write operation has been completed and is
waiting for the next command. See the Microprocessor Section of this datasheet for
details.
Host Mode (Serial Interface)
If Pin SER_PAR is pulled "High", this output pin from the serial interface is used to
read back the regsiter contents. See the Microprocessor Section of this datasheet for
details.
Hardware Mode
EQC[4:0] are used to set the Receiver Gain, Receiver Impedance and the Transmit
Line Build Out. See
Table 19
for more details.

Bi-Directional Data Bust/Loopback Mode Select
Host Mode
These pins are used for the 8-bit bi-directional data bus to allow data transfer to and
from the microprocessor interface.
Hardware Mode (Channels 4 through 7)
These pins are used to select the loopback mode. Each channel has two loopback
pins Loop[1:0].
"00" = No Loopback
"01" = Analog Local Loopback
"10" = Remote Loopback
"11" = Digital Loopback
