Write in Process
The contents of the Data Registers are saved to
nonvolatile memory when the CS pin goes from LOW
to HIGH after a complete write sequence is received
by the device. The progress of this internal write
operation can be monitored by a write in process bit
(WIP). The WIP bit is read with a read status
command.
INSTRUCTIONS
Identification (ID) Byte
The first byte sent to the X9250 from the host,
following a CS going HIGH to LOW, is called the
Identification byte. The most significant four bits of the
slave address are a device type identifier, for the
X9250 this is fixed as 0101[B] (refer to Figure 2).
The two least significant bits in the ID byte select one
of four devices on the bus. The physical device
address is defined by the state of the A0 - A1 input
pins. The X9250 compares the serial data stream with
the address input state; a successful compare of both
address bits is required for the X9250 to successfully
continue the command sequence. The A0 - A1 inputs
can be actively driven by CMOS input signals or tied to
VCC or VSS.
The remaining two bits in the slave byte must be set to 0.

Instruction Byte
The next byte sent to the X9250 contains the
instruction and register pointer information. The four
most significant bits are the instruction. The next four
bits point to one of the four pots and, when applicable,
they point to one of four associated registers. The
format is shown below in Figure 3.
