N11
XL1.5
O
(analog)
–
Transmit Line 1, port 5
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.
XOID5
O
–
Transmit Optical Interface Data, port 5
Data in CMI code is shifted out with 50% or 100% duty
cycle on both transitions of XCLK5 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.
N10
XL2.5
O
(analog)
–
Transmit Line 2, port 5
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.
P11
XL3.5
I (analog) –
Transmit Line 3, port 5
Analog transmit input 1.
P10
XL4.5
I (analog) –
Transmit Line 4, port 5
Analog transmit input 2.
N14
XL1.6
O
(analog)
–
Transmit Line 1, port 6
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.
XOID6
O
–
Transmit Optical Interface Data, port 6
. Data in CMI code is shifted out with 50% or 100% duty
cycle on both transitions of XCLK6 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.
N13
XL2.6
O
(analog)
–
Transmit Line 2, port 6
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.
P14
XL3.6
I (analog) –
Transmit Line 3, port 6
Analog transmit input 1.
P13
XL4.6
I (analog) –
Transmit Line 4, port 6
Analog transmit input 2.
