Field
31–0
Transmit mask. Indicates which transmit time slot has been masked in the current frame. Each bit corresponds
TMASK
to the respective time slot in the frame. If a change is made to the register contents, the transmission pattern is
updated from the next time slot. Transmit mask bits should not be used in I
0 Valid time slot
1 Time slot masked (no data transmitted in this time slot)
