3.7.2. Default behavior of EmbeddedICE watchpoint comparator inputs

When the EmbeddedICE Behavior Control Register is not implemented, Table 3.4 defines the behavior of any EmbeddedICE watchpoint comparator input connection to the different PTM resources.

Note

A debugger can read bit [21] of the Configuration Code Extension Register to find whether the EmbeddedICE Behavior Control Register is implemented:

  • If the register is not implemented the debugger can assume the EmbeddedICE watchpoint comparator inputs behave as Table 3.4 shows.

  • If the register is implemented the debugger must write to the register to configure the behavior of each EmbeddedICE watchpoint comparator input, as required for the use it is making of the input.
