Retry Count 1 and Retry Count 0
If BCRE (BC Retry Enable) bit 12 is logic 1 in the BC Configuration
Register 0x0032 and RTRYENA bit 8 is logic 1 in the BC Control Word
for this message, the BC will retry the message if RT response timeout or
Format Error occurs.
Also, if BCRE (BC Retry Enable) bit 12 is logic 1 and BCRSB (BC Retry
if Status Word Bits Set) bit 8 is logic 1 in the BC Configuration Register
0x0032 and RTRYENA bit 8 is logic 1 in the BC Control Word for this
message, the BC will retry the message when a “Status Set” condition
occurs. See “MSTATSET” bit 7 description above.
The combination of these two bits indicates the number of times this
message was retried:
Good Transmit Data Block Transfer.
This bit is set to logic 1 upon successful completion of an error-free RT-to-
BC message, RT-to-RT message, or transmit mode code message with
data. This bit always resets to logic 0 for any BC-to-RT message, mode
code message without data, or any incomplete or invalid message.
This bit may be used for determining when the transmit portion of an
RT-to-RT message is error-free. If this bit and Error Flag bit 12 are both
set to logic 1 in the Block Status Word for an RT-to-RT message, the
transmitting RT responded correctly but error occurred in the receiving RT
portion of the message.
Wrong RT Address and/or No Gap.
This bit is logic 1 when one or both of the following conditions occur
Word Count (Length) Error.
This bit is logic 1 when an RT-to-BC message, RT-to-RT message, or
transmit mode code message with data is transacted with the wrong
number of data words.
This bit always resets to logic 0 for BC-to-RT messages, receive mode
code messages, or transmit mode code messages without data.
Sync Error.
This bit is logic 1 when an RT responds with Data Sync in its Status Word,
or with Command/Status Sync in a Data Word.
