There are three points in the MPCore pipeline at which signals are produced for the ETM. These signals must be realigned by the ETM, so pipeline advance signals are provided.

The pipeline advance signals indicate when a new instruction enters pipeline stages Ex3, Ex2, and ADD, see Typical pipeline operations.

Table 14.7 shows the ETMPADV[2:0] pipeline advance interface signals.

The pipeline advance signals present in other interfaces are:
