The shift register bits are initialized to 0. Then, starting with the least significant bit of the family code,
one bit at a time is shifted in. After the eighth bit of the family code has been entered, the serial number is
entered. After the serial number has been entered, the shift register contains the CRC value. Shifting in
the eight bits of CRC returns the shift register to all 0s.

INPUT DATA
REGISTER ACCESS
The registers needed to operate the DS2408 are organized as a Register Page, as shown in Figure 5. All
registers are volatile, i. e., they lose their state when the device is powered down. PIO, Conditional
Search, and Control/Status registers are read/written using the device level Read PIO Registers and Write
Conditional Search Register commands described in subsequent sections and Figure 8 of this document.
