In Figure 10, a trigger level of 14 is selected. The control signal DATA_AV is set to an active low pulse. This
means that the connected processor has the task to read 14 values from the ADC after every DATA_AV low
pulse.

READ is always the logical combination of CS0, CS1 and RD.
ADC Control Register
The THS10064 contains two 10-bit wide control registers (CR0, CR1) in order to program the device into the
desired mode. The bit definitions of both control registers are shown in Table 7.

Writing to control register 0 and control register 1
The 10-bit wide control register 0 and control register 1 can be programmed by addressing the desired control
register and writing the register value to the ADC. The addressing is performed with the upper bits RA0 and RA1.
During this write process, the data bits D0 to D9 contain the desired control register value. Table 8 shows the
addressing of each control register.
