Abstract: A method is disclosed for generating a sequential pattern of motor control instructions under control of a microcontroller for the purpose of controlling a motor. A pattern of motor control instructions is stored in a memory. A timing circuit is operable to generate a periodic output sync signal. The microcontroller is operable to initiate a sequential Read operation of the memory so as to cause sequential reading and output of motor control instructions from the memory in a predetermined order. Each of the read motor control instructions is then stored in a pre-load buffer after output from the memory. The contents of the pre-load buffer is then transferred to an output buffer in synchronization with the output sync signal, wherein the output of motor control instructions from the memory is not required to be periodic.
