If you change the SJA1000, to the Microchip MCP25020, that
has 8 I/O and on chip config registers so can 'wake up alive'.

Simplest scheme to tranfer counter info, from a CPLD, would be
a nibble-ram map, where you allocate 4 of the I/O as Address, and
4io as read-back nibble.
A Write-Read CAN transaction, then Sends Address, and recovers one
firmly identified nibble, and 16 nibbles can map 8 bytes of info.
