Function
Transmit Line 2 Monitor
Analog input from the external transmit
transformer (XL2). This pin must be connected
otherwise the XL2 pin could be set in a high
impedance state. If digital inputs are selected
via LIM1.DRS = 1 this input has to be switched
to
Positive Power Supply for analog transmitter
Transmit Clock
Transmit clock frequency: 2048 kHz.
Derived from the SCLKX or RCLK or internally
generated.
If LIM1.EFSC is set high an 8-kHz Frame
Synchronization Pulse is output via this pin.
The synchronization pulse is active high for one
2 MHz cycle (pulse width = 488 ns) and derived
from clock supplied by pin XTAL1.
Not connected. For further application this pin
should be connected to
8-kHz Frame Synchronization Pulse is active
low for one 2 MHz cycle (pulse width = 488 ns)
and derived from the clock supplied by pin
XTAL1.
System Clock 16.384 MHz
System Clock 16.384 MHz only if a crystal or
an oscillator is connected to XTAL3/4.
System Clock 8.192 MHz
The frequency is derived from the clock
supplied by pin XTAL1.
System Clock Output
Output frequencies are: 2.048 MHz or
4.096 MHz inverted or non-inverted. The
frequency and sense on this pin is selectable
via LIM0.SCL1/0 and is derived from the clock
supplied by pin XTAL1.
