+ * All device handlers are scheduled by adding them into  Polling Sequence Tables (PST)
+ * to satisfy stricter timing requirements of device communication,
+ * A device handler has four different communication steps:
+ *   1. DeviceHandlerIF::SEND_WRITE -> Send write via interface
+ *   2. DeviceHandlerIF::GET_WRITE -> Get confirmation for write
+ *   3. DeviceHandlerIF::SEND_READ -> Send read request
+ *   4. DeviceHandlerIF::GET_READ -> Read from interface
+ * The PST specifies precisely when the respective ComIF functions are called
+ * during the communication cycle time.
+ * The task is created using the FixedTimeslotTaskIF,
+ * which utilises the underlying Operating System Abstraction Layer (OSAL)
+ *
+ * @param thisSequence FixedTimeslotTaskIF * object is passed inside the Factory class when creating the PST
+ * @return
