clocked by TSCCKB. The active edge of TSCCKB used to sample the
each time slot is the first bit to be transmitted.
Slave mode, the special feature in this mode is that the multi-functional
pin TSFSn/TSSIGn is used as TSFSn to output a framing pulse to indi-
cate the first bit of each Basic Frame.
Functional Description
Table 28: Active Edge Selection of TSCCKB (in E1 Transmit Clock
Slave TSFS Enable Mode)
Note:
If the FE is not equal to the DE, the active edge decided by the FE is one clock edge
before the active edge decided by the DE.
The FE (b3, E1-018H) of the eight framers should be set to the same value to ensure
TSCFS for the eight framers is sampled on the same active edge.
In this mode (refer to Figure 37), the data on the system interface is
