1. A motor control circuit to control a motor driver, comprising:
a first storage region; and
a second storage region, wherein
the first storage region stores a control algorithm of the motor control circuit and a first parameter group to be used by the control algorithm,
the second storage region can store a second parameter group to be used by the control algorithm,
the second storage region comprises a specification parameter to specify whether the first parameter group or the second parameter group is used by the control algorithm to execute a motor control program, and
the control algorithm reads a value of the specification parameter at a startup and executes the motor control program using the parameter group specified with the read value.
 
5. A control method for a motor control circuit comprising a first storage region storing a motor control circuit control algorithm and a first parameter group to be used by the control algorithm and a second storage region enabled to store a second parameter group to be used by the control algorithm, and configured to output a drive control signal to a motor driver, the method comprising:
referencing a value of a specification parameter in the second storage region when the control algorithm is started;
determining whether the first parameter group or the second parameter group is used by the control algorithm to execute a motor control program based on the value of the specification parameter; and
executing of the control algorithm the motor control program using the determined parameter group.
 
7. A motor control circuit to control a motor driver, comprising:
a first storage region; and
a second storage region, wherein
the first storage region stores a control algorithm of the motor control circuit and a first parameter group to be used by the control algorithm,
the second storage region can store a second parameter group to be used by the control algorithm, and
the control algorithm executes the motor control program using either the first parameter group or the second parameter group to output a drive control signal for controlling of driving of a motor to the motor driver.
