4.13.8.26 CM4_TRCCTI_LOCKSTATUS
Description:
Lock Status Register
Address:
0xE0080FB4
Offset:
0xFB4
Retention:
Retained
IsDeepSleep:
No
Comment:
This indicates the status of the Lock control mechanism. This lock prevents accidental writes
by code under debug.
This register must always be present although there might not be any lock-access control
mechanism. The lock mechanism, where present and locked, must block write accesses to
any control register, except the Lock Access Register. For most components this covers all
registers except for the Lock Access Register 0xFB0.
Default:
0x0
