Address Bus 4–0/G.772 Monitoring Control/Rx Impedance
Mode Select
A[4:0]:
These five pins are address pins in parallel host mode. In
serial host mode and multiplexed host mode, these pins should be
grounded.
RIMPMSB:
In hardware mode when this pin is low, the internal
impedance mode is selected, so RTIP and RING require no
external resistance component. When high, external impedance
mode is selected so RTIP and RING require external resistance.
GMC[3:0]:
In hardware mode, these signal pins are used to select
transmitter or receiver for nonintrusive monitoring. Receiver 1 is
used to monitor channels 2 to 8 of one receiver from RTIP2–
RTIP8/RRING2–RRING8 or one transmitter from TTIP2–
TTIP8/TRING2–TRING8. These signal pins correspond to the bits
in
Table 5-9
.
Output Enable.
If this pin is pulled low, all the transmitter outputs
(TTIP and TRING) are high impedance. Additionally, the user may
use this same pin to turn off all the impedance matching for the
receivers at the same time if register bit
GMR.RHPMC
is set.

Clock Edge.
When CLKE is high, SDO is valid on the falling edge
of SCLK. When CLKE is low SDO is valid on the rising edge of
SCLK. When CLKE is high, the RCLK for all the channels is
inverted. This aligns RPOS/RNEG on the falling edge of RCLK
and overrides the settings in register
RCLKI
. When low,
RPOS/RNEG is aligned on the settings in register
RCLKI
.

JTAG Test Mode Select.
This pin is clocked on the rising edge of

JTAG Test Clock.
The data JTDI and JTMS are clocked on rising
edge of JTCLK and JTDO is clocked out on the falling edge of
JTCLK.
