Function
Transmit Line 1, port 1
Analog output to the external transformer. Selected if
LIM1.DRS is cleared. After reset this pin is in high-
impedance state until bit MR0.XC1 is set and
XPM2.XLT is cleared.
Transmit Optical Interface Data, port 1
Data in CMI code is shifted out with 50% or 100% duty
cycle on both transitions of XCLK2 according to the CMI
coding. Output polarity is selected by bit LIM0.XDOS
(after reset: data is sent active high). The single-rail
mode is selected if LIM1.DRS is set and MR0.XC1 is
cleared. After reset this pin is in high-impedance state
until register LIM1.DRS is set and XPM2.XLT is cleared.
Transmit Line 2, port 1
Analog output for the external transformer. Selected if
LIM1.DRS is cleared. After reset this pin is in high-
impedance state until bit MR0.XC1 is set and
XPM2.XLT is cleared.
Transmit Line 1, port 2
Analog output to the external transformer. Selected if
LIM1.DRS is cleared. After reset this pin is in high-
impedance state until bit MR0.XC1 is set and
XPM2.XLT is cleared.
Transmit Optical Interface Data, port 2
Data in CMI code is shifted out with 50% or 100% duty
cycle on both transitions of XCLK2 according to the CMI
coding. Output polarity is selected by bit LIM0.XDOS
(after reset: data is sent active high). The single-rail
mode is selected if LIM1.DRS is set and MR0.XC1 is
cleared. After reset this pin is in high-impedance state
until register LIM1.DRS is set and XPM2.XLT is cleared.
Transmit Line 2, port 2
Analog output for the external transformer. Selected if
LIM1.DRS is cleared. After reset this pin is in high-
impedance state until bit MR0.XC1 is set and
XPM2.XLT is cleared.
