SSU register permissions vary depending on category and function. CPU1 is the primary owner of all SSU registers, including those for all other CPUs. Most registers are automatically loaded at device startup; however, some are designated for run-time operation, for example, FLSEM. The tables in this section describe the access permissions for each register, organized by register groups. For register access permission tables that do not include a column for the HSM, there is no HSM access permitted to these registers.
Accesses to SSU registers that are denied generate a fault to the ESM.
In SSUMODE1, CPU register read access is granted if any LINK is enabled for hardcoded read permissions. Similarly, in SSUMODE1 CPU register write access is granted if any LINK is enabled for hardcoded write permissions. This rule does not supersede Flash semaphore ownership rules.
