In ARMv6-M and ARMv7-M there are two processor modes available:
Thread mode
Handler mode.
Thread mode is the normal mode that programs run in. Thread mode can be privileged or unprivileged software execution. Handler mode is the mode that exceptions are handled in. The handler mode is always privileged software execution.
