4) skip ROM or 5) search interrupt. After a ROM function sequence has been successfully executed, the  
memory functions are accessible and the master may then provide any one of the four memory function  
commands (Figure 6).  
The “Power Control” section provides for two basic power configurations: battery operate mode and VCC  
operate mode. The battery operate mode utilizes one supply connected to VBATO. The VCC operate mode  
may utilize two supplies; the primary supply connects to VCC and a backup supply connects to VBATB  
.

COMMUNICATION PORTS  
Two communication ports are provided: a 1-Wire and a 3-wire port. The advantages of using the 1-Wire  
port are as follows: 1) provides access to the 64-bit lasered ROM, 2) consist of a single communication  
signal (I/O), and 3) multiple devices may be connected to the 1-Wire bus. The 1-Wire bus has a  
maximum data rate of 16.3kbits/s and requires one 5kΩ external pull-up.  
The 3-wire port consists of three signals: RST , CLK, and DQ. RST is an enable input, DQ is bidirectional  
serial data, and the CLK input is used to clock in or out the serial data. The advantages of using the  
3-wire port are 1) high data transfer rate (2MHz), 2) simple timing, and 3) no external pull-up required.
