Pulse Count Detection
A LOS alarm (red alarm) is detected if the incoming data stream has
no transitions for a programmable number T consecutive pulse
positions. The number T is programmable by the PCD register and
can be calculated as follows:
T = 16
The maximum time is: 256

the receive clock RCLK.

data from pins RL1/2 or RDIP/N or ROID is sent "jitter-free" on
ports XL1/2 or XDOP/N or XOID. The de-jittered clock is
generated by the DCO-X circuitry.
The ternary interface is selected. Multifunction ports RL1/2 and
XL1/2 become analog in/outputs.
The digital dual-rail interface is selected. Received data is
latched on multifunction ports RDIP/RDIN while transmit data is
output on pins XDOP/XDON.
