Transmit Time Tag for Synchronize Mode Code Command MC17.
This option bit only applies when BC Configuration Register TTSYNEN bit
3 is logic 1. See page 26. This bit affects only the “synchronize with data”
mode code command, (mode code 0x11 or decimal 17).
Message Error Bit Mask.
If this BC Control Word bit is logic 0 and the Message Error bit 10 is logic 1
in the received RT Status Word, a “Status Set” condition will result.
If this BC Control Word bit is logic 1, the Message Error bit 10 in the
received RT Status Word has no effect on the outcome for a “Status Set”
condition.
Note: A “Status Set” condition results if one or more of these events occurs:
Service Request Bit Mask.
If this BC Control Word bit is logic 0 and the Service Request bit 8 is logic 1
in the received RT Status Word, a “Status Set” condition will result.
If this BC Control Word bit is logic 1, the Service Request bit 8 in the
received RT Status Word has no effect on the outcome for a “Status Set”
condition.
See “Note” at end of MEMASK bit description above.

HOLT INTEGRATED CIRCUITS
If this Control Word bit is logic 0 (or if BC Configuration Register
TTSYNEN bit 3 is logic 0) the BC transmits the value contained in
the Message Data Block as the data word for a “synchronize” mode
code command MC17. The transmitted word is fetched from the RAM
address referenced by the Data Address Pointer.
If this Control Word bit and BC Configuration Register TTSYNEN bit
3 are both logic 1, the “synchronize” mode data word value originates
from the 16-bit BC time base counter (low order 16 bits when using the
32-bit BC time base option).
•
•
The transmitted data value is saved in the message data block, at the
address indicated by the Data Address Pointer word.
one or more of the mask bits 14-9 in the BC Control Word is logic 0 and
the corresponding bit is logic 1 in the received RT Status Word,
the BCRME bit 0 is logic 1 in the BC Configuration Register 0x0032 and
the MASKBCR bit in the BC Control Word is logic 0 and the Broadcast
Command Received bit 4 is logic 1 in the RT Status Word
the BCRME bit 0 is logic 0 in the BC Configuration Register 0x0032 and
the MASKBCR bit in the BC Control Word differs from the Broadcast
Command Received bit 4 in the RT Status Word
The received RT Status Word contains an RT Address field different
from the RT Address field in the transmitted Command Word
HI-6130, HI-6131
If BC Configuration Register ETTSYN bit 2 is also logic 1, the
transmitted time tag data word is always an even value; the least
significant bit is always 0.
When ETTSYN bit 2 is logic 0, the data word least significant bit
may be 0 or 1. See page 26.
