When the configuration lockdown feature is enabled:
• The lockdown feature can only be disabled by a component reset that resets CTRL[31] to
0x0
.
• The following registers are read-only:
— CTRL.
— BLK_LUT.
— INT_EN.
Note
Arm recommends that you write
0x1
to the LUT autoincrement bit, CTRL[8], before enabling the
configuration lockdown feature. When the feature is enabled, only LUT reading is available which is
simpler when BLK_IDX increments automatically during the read sequence.
