12.6 TRAIL TRACE IDENTIFIER PROCESS
12.6.1 TTI Formats
All performance counters are one second shadow counters: at the one second boundary the
contents of each performance counter is latched into its one second shadow register, after
which the performance counter is cleared. These one second shadow registers will hold their
value during the entire period between two subsequent one second boundaries.
The one second shadow registers are available for software read-only access.
All errored BIP and block counters are dimensioned to cover the maximum count value during
a one second interval meaning they can never reach saturation.
The one second boundary is generated by the internal one second clock which is either
derived from the PHAST-12N System Clock or from the external REFONESECCLK input lead.
The performance counters can be reset by writing 0x91 into the ResetCounters register.
The following TTI formats or modes are supported:

The following TTI message types are supported:
• 16-byte trace message: 16-byte repeating pattern consisting of a 15-byte APId preceded
• 64-byte trace message: a 64-byte repeating pattern consisting of a 63-byte APId pre-
• 64-byte trace message with CR/LF: a 64-byte repeating pattern consisting of a 62-byte
• repeating non-specific byte: a repeating single byte with fixed (constant), but unspecified
