After you are finished writing, the D*/A line goes low, indicating a data transfer to a register.
This enables the Address Handler output and selects the appropriate register.
At the end of each communication with the Module ID Register or the Data Register, select the
Parking Register (write address FFFF to the Address Handler). This increases the noise
immunity of the module when it is in its quiescent state. After you select the Parking Register,
SS* should go high, deselecting the module.
At reset or at power up, the Address Handler content is cleared.
