Figure 26. Timing for DSD Audio Interface
Register Read/Write Operation
All read/write operations for the serial control port use 16-bit data words. Figure 27 shows the control data word
format. The most significant bit is the read/write (R/W) bit. For write operations, the R/W bit must be set to 0. For
read operations, the R/W bit must be set to 1. There are seven bits, labeled IDX[6:0], that set the register index (or
address) for the read or write operations. The least significant eight bits, D[7:0], contain the data to be written to the
register specified by IDX[6:0] or to be read from the register specified by IDX[6:0].
Figure 28 shows the functional timing diagram for writing or reading the serial control port. MS is held at a logic 1
state until a register needs to be written or read. To start the register write or read cycle, MS is set to logic 0. Sixteen
clocks are then provided on MC, corresponding to the 16 bits of the control data word on MDI and read back data
on MDO. After the eighth clock cycle has completed, the data from indexed mode control register appears on MDO
in read operation. After the sixteenth clock cycle has completed, the data is latched into the indexed mode control
register in write operations. To write or read subsequent data, MS must be set to 1 once.
