1. An electronic control configuration, comprising:
- at least one secondary microprocessor operable to control a device, the at least one secondary microprocessor assuming protection control of the device responsive to a first type of failure by transmitting a protection control signal to a first effector, the at least one secondary microprocessor assuming backup control of the device responsive to a second type of failure by transmitting a backup control signal to a second effector, wherein the backup control functionality of the at least one secondary microprocessor can be selectively disabled.

Abstract
An electronic control configuration includes at least one secondary microprocessor operable to control a device. The at least one secondary microprocessor assumes protection control of the device responsive to a first type of failure by transmitting a protection control signal to a first effector. The at least one secondary microprocessor assumes backup control of the device responsive to a second type of failure by transmitting a backup control signal to a second effector. The backup control functionality of the at least one secondary microprocessor can be selectively disabled.

12. An electronic control configuration, comprising:
-
a first primary control operable to control a device; a first secondary control operable to assume protection control of the device if the first primary control experiences a first type of failure; a second primary control operable to control the device in response to the first primary control experiencing a second type of failure; and a second secondary control operable to assume protection control of the device if the second primary control experiences the first type of failure, at least one of the secondary controls being operable to assume backup control of the device if both the first and second primary controls experience the second type of failure. - View Dependent Claims (13, 14, 15, 16)
