In general a control word has the following format. Bit 0 is the Read/Write bit that determines whether it is

a read (R/W = 1) or a write (R/W = 0) sequence. The R/W bit is preceding the latch address and the

corresponding data bits.

R/W

There are two control word formats for read and for write operation. Data bits are only needed in write

mode. Read operations require only a latch address and a R/W bit.

Due to the static CMOS design, the serial interface consumes virtually no current. The SPI is a fully separate

building block and can therefore be programmed in every operational mode.
