Abstract: An N-bit control word may be parsed into individual control bits and the individual bits may be inserted into the least significant bit (“LSB”) of N data words. The respective LSBs of the N data words may be mapped into particular bit positions of a control register. When a device receives the N data words, the respective LSBs of the N data may be stored in their designated bit position of the control register. The sender need not specify the address of the control register.
