Motorola/Intel/Coder Mode Select Input
Parallel Host Mode -
When this pin is
Low
the micropro-
cessor interface is configured for operation with Motorola
processors. When this pin is
High
the microprocessor in-
terface is configured for operation with Intel processors.
Hardware Mode -
When the CS61884 is configured for uni-
polar operation, this pin, CODEN, configures the line
encoding/decoding function. When CODEN is low,
B8ZS/HDB3 encoders/decoders are enabled for T1/J1 or
E1 operation respectively. When CODEN is high, AMI en-
coding/decoding is activated. This is done for all eight
channels.

Transmitter Output Enable
Host mode -
Operates the same as in hardware mode. In-
dividual drivers can be set to a high impedance state via
the
Output Disable Register (12h)
(See Section 14.19 on
page 39).
Hardware Mode -
When TXOE pin is asserted Low, all the
TX drivers are forced into a high impedance state. All other
internal circuitry remains active.
CLKE

I
Clock Edge Select
In clock/data recovery mode, setting CLKE
high
will cause
RPOS/RNEG to be valid on the falling edge of RCLK and
SDO to be valid on the rising edge of SCLK. When CLKE is
set
low
, RPOS/RNEG is valid on the rising edge of RCLK,
and SDO is valid on the falling edge of SCLK. When the
part is operated in data recovery mode, the RPOS/RNEG
output polarity is active
high
when CLKE is set
high
and
active
low
when CLKE is set
low
.
