Functionality by Operating Mode

Supported functionality in each operating mode is given in Table 8-1.

Functional key:

  • EN: The function is enabled in the specified mode.
  • DIS: The function is disabled (either clock or power gated) in the specified mode, but the function's configuration is retained.
  • OPT: The function is optional in the specified mode, and remains enabled if configured to be enabled.
  • NS: The function is not automatically disabled in the specified mode, but it is not supported.
  • OFF: The function is fully powered off in the specified mode, and no configuration information is retained. When waking up from an OFF state, all module registers must be re-configured to the desired settings by application software.
