ADC CONTROL REGISTER
The THS1207 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 6.

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 data bits D10
and D11, which function in this case as address lines RA0 and RA1. During this write process, the data bits D0
to D9 contain the desired control register value. Table 7 shows the addressing of each control register.
