C11.46 Address Comparator Access Type Registers 0-7
The TRCACATRn characteristics are:
Purpose
Controls the access for the corresponding address comparators.
Usage constraints
Accepts writes only when the trace unit is disabled.
If software uses two single address comparators as an address range comparator then it must
program the corresponding TRCACATR registers with identical values in the following
fields:
TYPE
CONTEXTTYPE
EXLEVEL_S
EXLEVEL_NS
Configurations
Available in all configurations.

EXLEVEL_NS, [15:12]
Each bit controls whether a comparison can occur in Non-secure state for the corresponding
exception level. The possible values are:
0 The trace unit can perform a comparison, in Non-secure state, for exception level n.
1 The trace unit does not perform a comparison, in Non-secure state, for exception level
n.
The exception levels are:
Bit[12] Exception level 0.
Bit[13] Exception level 1.
Bit[14] Exception level 2.
Bit[15] Always RES0.
EXLEVEL_S, [11:8]
Each bit controls whether a comparison can occur in Secure state for the corresponding
exception level. The possible values are:
0 The trace unit can perform a comparison, in Secure state, for exception level n.
1 The trace unit does not perform a comparison, in Secure state, for exception level n.
The exception levels are:
