FRAMER LOOPBACK
When CCR1.7 is set to a one, the DS2153Q will enter a
Framer LoopBack (FLB) mode. This loopback is useful
in testing and debugging applications. In FLB, the
DS2153Q will loop data from the transmit side back to
the receive side. When FLB is enabled, the following
will occur:
1. data will be transmitted as normal at TTIP and
TRING
2. data off the E1 line at RTIP and RRING will be
ignored
3. the RCLK output will be replaced with the TCLK
input.
