The fail_address_high Register characteristics are:

Purpose

Returns the address, the upper 32-bits, of the first access that failed a region permission, after the interrupt was cleared.

Usage constraints

There are no usage constraints.

Configurations

Only available when the TZASC has an AXI address width of greater than 32 bits.

Attributes

See the register summary in Table 3.1.

Figure 3.8 shows the fail_address_high Register bit assignments.
