This register controls the scrubbing of all RAMs in the associated Redistributor.
The GICR_FCTLR characteristics are:
|Usage constraints||There are no usage constraints.|
|Configurations||Available in all GIC-600 configurations.|
|Attributes||See 4.4 Redistributor registers for control and physical LPIs summary.|
The following figure shows the bit assignments.
The following table shows the bit assignments.
Table 4-25 GICR_FCTLR bit assignments
0 = Allow Q-Channel accesses.
1 = Deny Q-Channel accesses.
One bit per clock gate:
0 = Use full clock gating.
1 = Leave clock running.
Note:CGO must be set if clock gates are not implemented.
Scrub in progress:
0 = No scrub in progress.
1 = Scrub in progress.
This bit is read and written by software. When a scrub is complete, the GIC clears the bit to 0.
