2. Command Input/Data Output Interface
Commands (data write operations) from the microcontroller must be transferred LSB first in the following order: first
the data and then the address.
To perform a data output (data read) operation, first issue a read mode setup command and then perform the read
access.

Data Read
To read the data at address 61h, first write the address and set up read mode by setting CE low temporarily. When CE
is set high again and then a CL is issued, the contents of the set register address will be output serially (LSB first)
from CMDOUT.
If read mode is set up, a read access must be performed.
