The TRCCCCTLR characteristics are:
- Purpose
- Sets the threshold value for cycle counting.
- Usage constraints
Only accepts writes when the trace unit is disabled.
This register must be programmed if TRCCONFIGR.CCI is set to
1.
- Configurations
- Available in all configurations.
- Attributes
A 32-bit RW trace register.
