Command/Response Timing
Figure 6 shows the command/response timing. At the
end of a GET command, the eIMR device waits two
SCLK cycles and then transmits the response on SO.

Control Commands
The following section details the operation of each con-
trol commands available in the eIMR device. In all
cases, the individual bits in each command are shown
with the most-significant bit (bit 7) on the left and the
least-significant bit (bit 0) on the right. Table 4 and Table
5 show a summary of default states and a summary of
control commands, respectively.
Note:
Data is transmitted and received on the serial
data lines least-significant bit first and most-significant
bit last.
