To read data from the 1-Wire line. Equivalent to executing eight 1-Wire Single Bit
commands with V = 1 (write-one time slot), but faster due to less I
Generates eight read-data time slots on the 1-Wire line and stores result in the
1-Wire Read Data Register.
1-Wire activity must have ended before the DS2465 can process this command.
Command code is not acknowledged if 1WB = 1 at the time the command code is
received and the command is ignored.
