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.
Attributes See the register summary in Table 13-3 on page 13-10.
