All register contents set to 0’s (asynchronous).
No data transfer.
Input data is clocked into input register (location Bit 23) and previous data shifts.
Input register bits 23 (LSB)—12 (MSB) are loaded into DAC A.
Input register bits 11 (LSB)—0 (MSB) are loaded into DAC B.
Input register bits 23 (LSB)—12 (MSB) are loaded into DAC A, and input register bits 11 (LSB)—0 (MSB)
are loaded into DAC B.
