hardware configuration option
The TLV571 can configure itself. This option is enabled when the WR pin is tied to ground and a dummy RD
signal is applied. The ADC is now fully configured. Zeros or default values are applied to both control registers.
The ADC is configured ideally for 3-V operation, which means the internal OSC is set at 10 MHz and hardware
start of conversion using CSTART.
ADC conversion modes
The TLV571 provides two start of conversion modes. Table 1 explains these modes in more detail.
