Address offset: 0x088
Use this to set, or read, the single address comparators that control the ViewInst start/stop logic. The start/stop logic is active for an instruction which causes a start and remains active up to and including an instruction which causes a stop, and then the start/stop logic becomes inactive.
Might ignore writes when the trace unit is enabled or not idle.
If implemented then this register must be programmed.
