Description
Pulse Count Detection
A LOS 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 x (N+1); with 0 N 255.The maximum time is: 256 x 16 x 488 ns
= 2 ms. Every detected pulse resets the internal pulse counter. The
counter is clocked with the receive clock RCLK.
