Mailbox command - Reference
Get transm.err.counters (GET_TEC_X, 0x66)
This command is used to read out the status of the n error counters starting
from a particular slave address (cf. Chapter 2.1.1.10.2 "Protocol analysis: ").
The error counters are restarted each time the status of the counters is read out.
The status of the counters is read out via the appropriate host interface and
reset with each read access. The highest valid instantaneous status of the
counter is 254. A count of 255 indicates a counter overflow.
