FUNCTION
RLPIN
CCR2.7
RCL/LOTC Pin Function 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 0 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 1 redefines the operation of the transmit line
driver. When this bit is set to 1 and CCR4.5 = CCR4.6 = CCR4.7 = 0, the device generates a
square wave at the TTIP and TRING outputs instead of a normal waveform. When this bit is
set to 1 and CCR4.5 = CCR4.6 = CCR4.7
≠ 0, the device forces TTIP and TRING outputs to
become open-drain drivers instead of their normal push-pull operation. This bit should be set
to 0 for normal operation of the device. Contact the factory for more details about how to use
this bit.
RHBE
CCR2.3
Receive HDB3/B8ZS Enable
0 = enable HDB3 (E1)/B8ZS (T1)
1 = disable HDB3 (E1)/B8ZS (T1)
THBE
CCR2.2
Transmit HDB3/B8ZS Enable
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.
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.
0 = update RPOS and RNEG on rising edge of RCLK
1 = update RPOS and RNEG on falling edge of RCLK
