11.1 T1 Bit-Oriented Code (BOC) Controller
The DS26503 contains a BOC generator on the transmit side and a BOC detector on the receive side. The
BOC function is available only in T1 mode. In typical BITS applications, the BOC controller would be
used to transmit and receive Synchronization Status Messages in T1 mode over the data link.
11.2 Transmit BOC
Bits 0 through 5 in the TFDL register contain the BOC or synchronization status message to be
transmitted. Setting BOCC.0 = 1 causes the transmit BOC controller to immediately begin inserting the
BOC sequence into the FDL bit position. The transmit BOC controller automatically provides the abort
sequence. BOC messages will be transmitted as long as BOCC.0 is set. TFSE (T1TCR2.6) must be set =
0 when using the transmit BOC function.
To transmit a BOC, use the following:
1) Write 6-bit code into the TFDL register.
2) Set SBOC bit in BOCC register = 1.
