DS2405
device is not found using an active-only search, CONTROL must be a logical 0 and the PIO pin is being
held low by some other device or perhaps a fault condition such as a PIO shorted to ground. A second
fault condition may be detected if Search ROM for a given device returns read-1 time slots (PIO=logical
1) but Active-Only Search ROM is successful (CONTROL=logical 1) and returns read-0 time slots for
the same device, indicating the possibility that PIO may be shorted to a positive voltage.
