About this programmers model
The Juno r2 SoC programmers model derives from the ARMv8-A compute subsystem architecture that
supports ARMv8-A AARch64 software and tooling.
The following information applies to the SCC registers and to the system configuration, SYS_CFG,
registers:
• The base address is not fixed, and can be different for any particular system implementation. The
offset of each register from the base address is fixed.
• Do not attempt to access reserved or unused address locations. Attempting to access these locations
can result in
UNPREDICTABLE
behavior.
• Unless otherwise stated in the accompanying text:
— Do not modify undefined register bits.
— Ignore undefined register bits on reads.
— All register bits are reset to a logic 0 by a system or powerup reset.
