12.3 D4/SLC-96 OPERATION
In the D4 framing mode, the DS2152 uses the TFDL register to insert the Fs framing pattern. To allow
the device to properly insert the Fs framing pattern, the TFDL register at address 7Eh must be
programmed to 1Ch and the following bits must be programmed as shown:
Since the SLC-96 message fields share the Fs-bit position, the user can access these message fields via
the TFDL and RFDL registers. See the separate application note for a detailed description of how to
implement an SLC-96 function.
TCR1.2 = 0 (source Fs data from the TFDL register)
CCR2.5 = 1 (allow the TFDL register to load on multiframe boundaries)
