TEOC[12:8]
TEOC[12:0]
The Transmit Embedded Operations Channel (TEOC) holds 13 EOC bits for transmission in
the next frame. (Refer to Table 3-2 for EOC bit positions within the frame.) The HOH
multiplexer samples TEOC coincident with the respective HDSL channel’s transmit 6 ms
frame interrupt. Unmodified registers repeatedly output their contents in each frame.

TIND[12:8]
TIND[12:0]
The Transmit Indicator holds 13 IND bits for transmission in the next frame and includes the
FEBE bit (TIND[1]). (Refer to Table 3-2 for IND bit positions within the frame.) The HOH
multiplexer samples TIND coincident with the respective HDSL channel’s transmit 6 ms frame
interrupt. Unmodified registers repeatedly output their contents in each frame. TIND[0] is
transmitted first.
NOTE:
The RS8953B does not automatically output FEBE. Proper transmit of FEBE requires
the MPU to copy the CRC_ERR bit from STATUS_2 [addr 0x06] to TIND[1].
