To program the transmit output pulse, once the arbitrary pulse has been selected, write the appropriate values
into the segment registers in
Table 12
.
The transmit output pulse is divided into eight individual segments. Segment 1 corresponds to the beginning of
the pulse and segment 8 to the end of the pulse. The value for each segment can be programed individually
through a corresponding 8-bit register. In normal operation, i.e., non-arbitrary mode, codes are stored in an
internal ROM and are used to generate the pulse shape, as shown in
Table 12
. Typical ROM values are given
below in Hex.
Setting Registers to select an Aribtrary Pulse
N
OTE
:
The same register bank (eight registers in total) holds the values for any given line length. In other words , the user
can not load all the desired values for all the line lengths into the device at one time. If the line length is changed,
new codes must be loaded into the register banks.
4.7
DMO (Digital Monitor Output, Line Side Only)
The driver monitor circuit is used to detect transmit driver failures by monitoring the activities at TTip/TRing
outputs. Driver failure may be caused by a short circuit in the primary transformer or system problems at the
transmit inputs. If the transmitter of a channel has no output for more than 128 clock cycles, DMO is set "High"
until a valid transmit pulse is detected. If the DMO interrupt is enabled, the change in status of DMO will cause
the interrupt pin to go "Low". Once the status register is read, the interrupt pin will return "High" and the status
register will be reset (RUR).
