18.2LEGACY FDL SUPPORT
18.2.1 Overview
The DS2196 maintains the circuitry that existed in the previous generation of Dallas Semiconductor’s
single chip transceivers and quad framers. Section 18.2 covers the circuitry and operation of this legacy
functionality. In new applications, it is recommended that the HDLC controller and BOC controller
described in Section 18.1 be used. On the receive side, it is possible to have both the new HDLC/BOC
controller and the legacy hardware working at the same time. However this is not possible on the
transmit side since there can be only one source the of the FDL data internal to the device.
18.2.2 Receive Section
In the receive section, the recovered FDL bits or Fs bits are shifted bit–by–bit into the Receive FDL
register (RFDL). Since the RFDL is 8 bits in length, it will fill up every 2 ms (8 times 250 us). The
framer will signal an external microcontroller that the buffer has filled via the SR2.4 bit. If enabled via
IMR2.4, the INT pin will toggle low indicating that the buffer has filled and needs to be read. The user
has 2 ms to read this data before it is lost. If the byte in the RFDL matches either of the bytes
programmed into the RMTCH1 or RMTCH2 registers, then the SR2.2 bit will be set to a 1 and the INT
pin will toggled low if enabled via IMR2.2. This feature allows an external microcontroller to ignore the
FDL or Fs pattern until an important event occurs.
The framer also contains a zero destuffer, which is controlled via the CCR2.0 bit. In both ANSI T1.403
and TR54016, communications on the FDL follows a subset of a LAPD protocol. The LAPD protocol
states that no more than five 1’s should be transmitted in a row so that the data does not resemble an
