Table 2. Command Bytes
The devices include four registers accessible by 7
command bytes. The command bytes provide read
and write access to the Data Rate Control register, the
Sampling Instant Control register, and the Configuration
register, and read access to the Data register. See
Table 2. Figure 9 shows the CASCIN and CASOUT
timing diagram. Figure 10 is the XIN clock, CLKOUT,
SYNC, and DRDYOUT timing diagram.
*All data lengths are proportional to the number of cascaded
devices except for reads and writes to the Data Rate Control
register. When accessing the Data Rate Control register, the
data length is fixed at 16 bits. These 16 bits are automatically
written to all cascaded devices.
**n is the total number of cascaded devices.
