MB86R02 'Jade-D' Hardware Manual V1.64
Restrictions in global call address transmission at using multi master
If this module is used as a multimaster, it is prohibited for other masters to send a global call address at
the same time as this module and it loses arbitration at the 2nd byte or later.
The following usage does not fall under this restriction.
• This module is used in a single master environment.
• This module is used in a multimaster environment, however it does not send a general call
address.
• This module is used in a multimaster environment, however other modules do not use a
general call address transmission.
• Although this module is used in a multimaster environment and other masters send general
call address simultaneously with this module, it does not lose arbitration at the 2nd byte or
later.*
*: Because the larger transmission data causes an 'arbitration lost', the data of the 2nd byte or later
must always be smaller than the value of the other masters' data.
