INTN signal is suppressed. Only after the completion of the reading cycle the ASSP returns to the normal condition and updates the MSR-
register immediately if a new AD-conversion has been finished during data transfer.
The master unit does not detect any bus conditions since it generates them. Data transfer conditions (direction, register address and register
data) must not be changed until the current condition is over. The slave unit does not detect start and exception condition when master-read is
in progress.
The exception condition is reserved for future use and should be avoided.

Data transfers
Generally the SDI interface is active in all ASSP modes. For security reasons some write operations are restricted to certain modes. Read
operations are never disabled in order to keep consistent sdat driving conditions.
Writing to the result, trimming and calibration registers (MSR, CAR and TRR) is allowed only in test modes.
Writing to the Zener-Zap register is allowed only in mode MZP.
The first data bit after the start condition in each data transfer defines the data direction: sdat=high is used for master-read data (mr) condition
and sdat=low for master-write data (mw) condition.
Data is transferred with the most significant bit (MSB) first. Data bits are composed of register address and register data bits. Register address
is transmitted first, followed by the register data bits. The register address is always 4 bits long. The number of register data bits in table 7.5 is
implied by the register address.

The ASSP supports the data transfers presented in Table 8.1.
