This device supports an Arm® CoreSight™ compliant four-channel programmable on-chip Cross Triggering network. In addition to the four-channel on-chip network, this device implements two channels of product level triggering via the EMU0 and EMU1 device pins.
Conceptually, each channel of Cross Triggering can be viewed as mapping of a user-defined set of events to a user-defined set of actions, where the occurrence of any event in the set-of-events results in the generation of the set-of-actions. Table 13-9 provides a domain-level summary of the supported events and actions.
| Domain | Events | Actions |
|---|---|---|
| Product-Level | Zero detected on EMU0 input pin | EMU0 output pin driven to Zero |
| Zero detected on EMU1 input pin | EMU1 output pin driven to Zero | |
