LOW-IMPEDANCE DQ DURING COMPUTATION
The SHA-1 computation requires more current than the DQ pullup resistor used during normal communication can
supply. During the computation, the DQ source impedance must be reduced to maintain power to the device under
the higher load condition. The user must connect the low impedance source to the DQ line within t
D
of issuing any
command to perform a computation, and return the DQ source to normal settings before reading or writing to the
one-wire interface. See Figure 9.
