3-WIRE (SPI COMPATIBLE) SERIAL CONTROL INTERFACE MODE

SDIN is used for the program data, SCLK is used to clock in the program data and /CS is use to

latch in the program data. SDIN is sampled on the rising edge of SCLK. The 3-wire interface write

protocol is shown in Figure 10.

Figure 10 3-Wire Serial Interface Write Protocol

•

W indicates write operation.

•

A[6:0] is the register index.

•

B[15:0] is the data to be written to the register indexed.

•

/CS is edge sensitive – the data is latched on the rising edge of /CS.

The read-only status registers can be read back via the SDOUT pin. Read Back is enabled when the

R/W bit is high. The data can then be read by writing to the appropriate register address, to which the

device will respond with data.

Figure 11 3-Wire Serial Interface Readback Protocol

Any write to register R0 (00h) will reset the WM8593. All register bits are reset to their default values.
