The EDACR characteristics are:
Allows implementations to support IMPLEMENTATION DEFINED controls.
It is IMPLEMENTATION DEFINED whether EDACR is implemented in the Core power domain or in the Debug power domain. RW fields in this register reset to architecturally UNKNOWN values, and:
Changing this register from its reset value causes IMPLEMENTATION DEFINED behavior, including possible deviation from the architecturally-defined behavior.
If the EDACR contains any control bits that must be preserved over power down, then these bits must be accessible by the external debug interface when the OS Lock is locked, OSLSR_EL1.OSLK == 1, and when the Core is powered off.
EDACR is a 32-bit register.
The EDACR 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 |
