Trace channel	Width	Signed range
TRACE_1	32-bit	-2,147,483,648..2,147,483,647
TRACE_2	32-bit	-2,147,483,648..2,147,483,647
TRACE_3	32-bit	-2,147,483,648..2,147,483,647
TRACE_4	16-bit	-32,768..32,767
TRACE_5	16-bit	-32,768..32,767
TRACE_6	16-bit	-32,768..32,767

Values written to TRACE_4..TRACE_6 cannot preserve a full 32-bit integer. Use TRACE_1..TRACE_3 for large counters, masks, timestamps, or persistent values. Trace the state boundary relevant to the bug: physical input, transformed value, final output, mode, index, timer, or dirty flag.
