FUNCTION
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.
