Table 35. Bits 15:9 of T8531 Board Control Word 2 at 0x1FFC
Table 36. Bits 8:0 of T8531 Board Control Word 2 at 0x1FFC
Note:
Bits 15 through 9 are not used; assumed to be zeros. BOF[8:0] provide a fixed offset, relative to the frame synchronization strobe (SFS),
for the first bit transmitted in each time slot. The offset is the number of data periods by which transmission of the first bit on SDX is
delayed. All subsequent transmissions also follow this offset. The default value after hardware reset or powerup is 1A3; however, this reg-
ister must still be written after reset.
Table 37. Bits 15:0 of T8531 Board Control Word 3 at 0x1FFA
Note: For test use only, do not use in normal operation. The default value after hardware reset or powerup is 0.
Table 38. Bits 15:0 of T8531 Board Control Word 4 at 0x1FF8
Note: The default value after hardware reset or powerup is A4.
Table 39. Bits 15:0 of T8531 Board Control Word 5 at 0x1FF6
Note: The default value after hardware reset or powerup is 0.
