DESCRIPTION
P25S
CCR2.7
Pin 25 Select. Forced to logic 0 in hardware mode.
0 = toggles high during a Receive Carrier Loss condition
1 = toggles high if TCLK does not transition for at least 5
s.
-
CCR2.6
Not Assigned. Should be set to zero when written to.
SCLD
CCR2.5
Short Circuit Limit Disable (ETS = 0). Controls the 50mA
(RMS) current limiter.
0 = enable 50mA current limiter
1 = disable 50mA current limiter
CLDS
CCR2.4
Custom Line Driver Select. Setting this bit to a one will
redefine the operation of the transmit line driver. When this bit
is set to a one and CCR4.5 = CCR4.6 = CCR4.7 = 0, then the
device will generate a square wave at the TTIP and TRING
outputs instead of a normal waveform. When this bit is set to a
one and CCR4.5 = CCR4.6 = CCR4.7
≠ 0, then the device will
force TTIP and TRING outputs to become open drain drivers
instead of their normal push-pull operation. This bit should be
set to zero for normal operation of the device. Contact the
factory for more details on how to use this bit.
RHBE
CCR2.3
Receive HDB3/B8ZS Enable. See Figure 1-2.
0 = enable HDB3 (E1)/B8ZS (T1)
1 = disable HDB3 (E1)/B8ZS (T1)
THBE
CCR2.2
Transmit HDB3/B8ZS Enable. See Figure 1-3.
0 = enable HDB3 (E1)/B8ZS (T1)
1 = disable HDB3 (E1)/B8ZS (T1)
TCES
CCR2.1
Transmit Clock Edge Select. Selects which TCLK edge to
sample TPOS and TNEG. See Figure 1-3.
0 = sample TPOS and TNEG on falling edge of TCLK
1 = sample TPOS and TNEG on rising edge of TCLK
RCES
CCR2.0
Receive Clock Edge Select. Selects which RCLK edge to
update RPOS and RNEG. See Figure 1-2.
0 = update RPOS and RNEG on rising edge of RCLK
1 = update RPOS and RNEG on falling edge of RCLK
