SERIAL INTERFACE The I 2 C-compatible interface operates in all three speed modes. Standard mode (100kHz) and Fast mode (400kHz) are functionally the same and will be referred to as Standard- Fast mode in this document. High-Speed mode (3.4MHz) ...
Page 16
High-Speed (Hs) Mode For Hs-mode, the sequence of events to begin communica- tion differ slightly from Standard-Fast mode. Figure 5 de- scribes this in further detail. Initially, the bus begins running in Standard-Fast mode. The master generates a Start ...
Page 17
Writing to the DAC Register To write to the DAC, the master addresses the part with the correct slave address (A6-A0) and writes a "zero" to the read/write bit. If addressed correctly, the DAC returns an ACK to the ...
Page 18
DAC REGISTER The DAC register, Figure 8, has sixteen bits. The first two bits are always zero. The next two bits determine the mode of operation (normal mode or one of three power-down modes). The final twelve bits of ...
