’DAC26 COMMUNICATION PROTOCOL
Register Programming
The ’DAC26 is entirely controlled by registers. An SPI master controlls the reading and writing of these registers by the
use of a 16-bit command, which is sent prior to the data for that register. The command is constructed as shown in Figure 19.
The command word begins with a R/W bit, which specifies the direction of data flow on the SPI serial bus. The following
four bits specify the page of memory this command is directed to, as shown in Table 2. The next six bits specify the register
address on that page of memory to which the data is directed. The last five bits are reserved for future use and should be
written only with zeros.

To read all the first page of memory, for example, the host processor must send the command 0x8000 to the ’DAC26 – this
specifies a read operation beginning at page 0, address 0. The processor can then start clocking data out of the ’DAC26.
The ’DAC26 automatically increments its address pointer to the end of the page; if the host processor continues clocking
data out past the end of a page, the ’DAC26 sends back the value 0xFFFF.
Likewise, writing to page 1 of memory consists of the processor writing the command 0x0800, which specifies a write
operation, with PG0 set to 1, and all the ADDR bits set to 0. This results in the address pointer pointing at the first location
in memory on Page 1. See the section on the ’DAC26 memory map for details of register locations
