12.5.22 XTDM Register (Offset = B8h) [reset = 0h]
XTDM is shown in Figure 12-25 and described in Table 12-27.
Return to Summary Table.
The transmit TDM time slot register (XTDM) specifies in which TDM time slot the transmitter is active.
TDM time slot counter range is extended to 384 slots (to support SPDIF blocks of 384 subframes). XTDM
operates modulo 32, that is, XTDMS specifies the TDM activity for time slots 0, 32, 64, 96, 128, and so
forth.
