1-Wire Receive Block, e.g., to Read Data from the 1-Wire Slave
Case A: 1-Wire Idle (1WB = 0)
S A A PAD,0 1WRB (Idle)A A<byte>60h
The parameter byte is always acknowledged, regardless of its value (is always valid).
Case B: 1-Wire Busy (1WB = 1)
S A A PAD,0 1WRB A\60h
The master should stop and restart as soon as the DS2465 does not acknowledge the command code.
