7.5 Programming

The device features nine configuration registers (as described in the Register Maps section) and supports two

types of data transfer operations: data write (the host configures the device), and data read (the host reads data

from the device).

7.5.1 Data Transfer Frame

A data transfer frame between the device and the host controller begins at the falling edge of the CONVST/CS

pin and ends when the device starts conversion at the subsequent rising edge. The host controller can initiate a

data transfer frame by bringing the CONVST/CS signal low (as shown in Figure 7-25) after the end of the CONV

phase, as described in the CONV State section.
