Secondary Serial Communication
Secondary serial communication is used to read or write 16-bit words that program both the options and the circuit
configurations of the device. Register programming always occurs during secondary communication. Four primary
and secondary communication cycles are requested to program the four registers. If the default value for a particular
register is desired, then the register addressing can be omitted during secondary communications. The NOOP
command addresses a pseudo-register (register 0), and no register programming takes place during this secondary
communication. If secondary communication is desired for any device (either master or slave), then a secondary
communication must be requested for all devices, starting with the master. This results in a secondary frame-sync
(FS) for all devices. The NOOP command can be used for devices that do not need a secondary operation.
During a secondary communication, a register can be written to or read from. When writing to a register, DIN contains
the value to be written. The data returned on DOUT is + 0000000000000 (3-bit device address).
There are two methods of initiating a secondary communication, as illustrated in Figure 3–2:
Asserting a high level on FC (hardware request)
Asserting the LSB of the DIN 16-bit serial communication high while in the 15-bit mode (software request)
NOTE:The secondary communication request should not be asserted during the first two
samples after power up.

Figure 3–2. Hardware and Software Secondary Communication Request
Pulling FC high causes the start of the secondary communications 128 or 256 SCLKs (see Figures 2–2 and 2–4) after
the start of the primary communication frame, depending on the number of devices in cascade.
The second method to initiate a secondary communication is asserting the LSB high. A software request is typically
used when the request resolution of the DAC channel is less than 16 bits. Then the least significant bit (D0) can be
used for secondary requests, as shown in Table 3–1. The request is made by placing the device in the 15-bit DAC
mode and making the LSB of DIN high. All cascading devices must be in 15-bit DAC mode, and set their LSBs to 1s
for requesting software secondary communication.
