The idle time is needed for the 1-Wire function to complete. Then set the read pointer to the Read Data register
(code E1h) and access the device again to read the data byte that was obtained from the 1-Wire line.

The read pointer is set to the Read Data register (code E1h) while the 1-Wire Read Byte command is still in prog-
ress. Then, after the 1-Wire function is completed, the device is accessed to read the data byte that was obtained
from the 1-Wire line.

Poll the Status segister until the 1WB bit has changed from 1 to 0. Then set the read pointer to the Read Data reg-
ister (code E1h) and access the device again to read the data byte that was obtained from the 1-Wire line.
