PRODUCTION DATA
All single write/read operations via the serial control port use 16-bit data words. Figure 7-26 shows the control data word format. The first bit is for read/write control, where 0 indicates a write operation and 1 shows a read operation. The next seven bits, labeled ADR[6:0], set the register address for the write/read operation. The least significant eight bits, D[7:0] on MDI or MDO, contain the data to be written to (or read from) the register specified by ADR[6:0].
