The GICD_STATUSR characteristics are:
Provides software with a mechanism to detect:
This register is part of the GIC Distributor registers functional group.
In an implementation that supports two Security states, there are separate Secure and Non-secure instances of this register:
Security disabled | Secure | Non-secure | |
---|---|---|---|
GICD_STATUSR(S) | RW | RW | - |
GICD_STATUSR(NS) | RW | - | RW |
This is an optional register. If the register is not implemented, the location is RAZ/WI.
If the GIC implementation supports two Security states this register is Banked to provide Secure and Non-secure copies.
GICD_STATUSR is a 32-bit register.
The GICD_STATUSR bit assignments are:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | WROD | RWOD | WRD | RRD |
