1
The SDO output shifts out the last 24 bits of data clocked into the serial register for daisy-chain operation. Exception: for any instruction following Instruction 9 or
Instruction 10, the selected internal register data is present in Data Byte 0 and Data Byte 1. The instructions following Instruction 9 and Instruction 10 must also be a
full 24-bit data-word to completely clock out the contents of the serial register.
2
The RDAC register is a volatile scratchpad register that is refreshed at power-on from the corresponding nonvolatile EEMEM register.
3
Execution of these operations takes place when the CS strobe returns to logic high.
4
Instruction 3 writes two data bytes (16 bits of data) to EEMEM. In the case of Address 0 and Address 1, only the last 10 bits are valid for wiper position setting.
5
The increment, decrement, and shift instructions ignore the contents of the shift register, Data Byte 0 and Data Byte 1.
