PD Rev 4.0 January 2006

CONTROL INTERFACE OPERATION

The WM8590 is controlled by writing to registers through a serial control interface. A control word

consists of 16 bits. The first 7 bits (B15 to B9) are address bits that select which control register is

accessed. The remaining 9 bits (B8 to B0) are data bits, corresponding to the 9 bits in each control

3-WIRE (SPI COMPATIBLE) SERIAL CONTROL

While CE is low, every rising edge of CL clocks in one data bit from the DI pin. A rising edge on CE

latches in a complete control word consisting of the last 16 bits. The 3-wire interface protocol is

shown in Figure 19.

B[15:9] are Control Address Bits

B[8:0] are Control Data Bits

CE is edge sensitive – the data is latched on the rising edge of CE.
