In addition to mut and obd logging, almost all firmware (H8, SH7052, SH7055, m32r) contain built-in dma logging mode. More than 8 modes.
Some of them are 100 hz (24 variables of 2 bytes each), 200 hz (24 variables of 1 byte each) and 800 hz (5 variables of 2 bytes each).
Logging is available both from the mut table (mt + at) and any request from RAM memory.

Thanks for the info! If I'm not mistaken the AUD can R/W at 1/4 of the processor speed. I haven't even looked at writing the protocol yet though, so I'm not sure about different addresses in a single request.
