Abstract
A control apparatus includes a storage that stores multiple parameters, a nonvolatile memory that is rewritable, and a control circuit that writes on the nonvolatile memory a target parameter from among the parameters. The parameter includes a parameter address indicating a storage location on the storage and at least one piece of parameter data. A control bit that is 0 or 1 is arranged in a parameter address or parameter data. The control circuit writes the parameter if the control bit is 1.
Claims10
A control apparatus comprising:
- a storage that stores a plurality of parameters,
- a nonvolatile memory that is rewritable, and
- a control circuit that writes on the nonvolatile memory a parameter serving as a write target from among the parameters,
- wherein the parameter includes a parameter address indicating a storage location on the storage and at least one piece of parameter data,
- wherein the parameter address or the parameter data includes a control bit that is 0 or 1, and
- wherein the control circuit writes the parameter on the nonvolatile memory if the control bit is 1.
A control method of a control apparatus including a storage that stores a plurality of parameters, a nonvolatile memory that is rewritable, and a control circuit that writes on the nonvolatile memory a parameter serving as a write target from among the parameters, comprising:
- an address reading step of reading an address in an unwritten area on the nonvolatile memory, on which the parameter has been written, the parameter including a parameter address indicating a storage location on the storage and at least one piece of parameter data,
- a parameter reading step of reading the parameter stored on the storage,
- a write determination step of determining with the control circuit, in accordance with a control bit that is 0 or 1 and arranged in the parameter address or the parameter data, whether to write the read parameter at the address in the unwritten area on the nonvolatile memory, and
- a write step of writing, if the control bit is 1, with the control circuit, the parameter read in the parameter reading step onto the nonvolatile memory.
