3.7. EmbeddedICE watchpoint comparator inputs

It is implementation defined whether a PTM implements any Embedded ICE watchpoint comparator inputs. If it does:

To find the number of EmbeddedICE comparator inputs implemented, read bits [19:16] of the Configuration Code Extension Register. See Configuration Code Extension Register, ETMCCER. If this field reads-as-zero then the implementation does not include any EmbeddedICE comparator inputs.

When a PTM implements one or more EmbeddedICE comparator inputs:

The following sections give additional information about the behavior of the EmbeddedICE watchpoint comparator inputs:
