A transmission code which packs six bits of data and four control vectors into an eight-hit format is presented. Scan test instruction data is loaded into an instruction register of a test access port TAP, the instruction data including information for selecting the alternative test circuitry. The control device responds to the signal received by the receiver and performs the first option if the distance between the remote control transmitter and the receiver is greater than a particular distance and performs a function based on the ambient noise level. A control bit generator determines a ratio control bit to be transmitted to the mobile station according to the erasure rate, to issue a command to increase or decrease a CQICH traffic-to-pilot ratio. The method comprises transforming a plant cell to contain a heterologous nucleotide sequence operably linked to the stress-responsive promoter of the present invention and regenerating a stably transformed plant from the transformed plant cell.
