The Write command is a 16-bit command. The format
of the command is shown in
A Write command to a Volatile memory location
changes that location after a properly formatted Write
Command (16-clock) have been received.

The write operation requires that the CS pin be in the
active state (V
the inactive state (V
(V
Data Byte) is then clocked in on the SCK and SDI pins.
Once all 16 bits have been received, the specified
volatile address is updated. A write will not occur if the
write command isn’t exactly 16 clocks pulses. This
protects against system issues from corrupting the
memory locations.
