DETAILED OPERATION
All EEPOT potentiometers share the serial interface and
share a common architecture. Each potentiometer has a
Wiper Counter Register and four data registers. A
detailed discussion of the register organization and array
operation follows.
Wiper Counter Register
The X9408 contains four Wiper Counter Registers, one
for each EEPOT potentiometer. The Wiper Counter
Register can be envisioned as a 6-bit parallel and serial
load counter with its outputs decoded to select one of
sixty-four switches along its resistor array. The contents
of the WCR can be altered in four ways: it may be written
directly by the host via the Write Wiper Counter Register
instruction (serial load); it may be written indirectly by
transferring the contents of one of four associated data
registers via the XFR Data Register instruction (parallel
load); it can be modified one step at a time by the
Increment/ Decrement instruction. Finally, it is loaded
with the contents of its data register zero (R0) upon
power-up.
The WCR is a volatile register; that is, its contents are
lost when the X9408 is powered-down. Although the
register is automatically loaded with the value in R0 upon
power-up, it should be noted this may be different from
the value present at power-down.
Data Registers
Each potentiometer has four nonvolatile data registers.
These can be read or written directly by the host and
data can be transferred between any of the four data
registers and the control latch. It should be noted all
operations changing data in one of these registers is a
nonvolatile operation and will take a maximum of 10ms.
If the application does not require storage of multiple
settings for the potentiometer, these registers can be
used as regular memory locations that could possibly
store system parameters or user preference data.
Register Descriptions
Data Registers, (6-bit), non-volatile:
Four 6-bit Data Registers for each EEPOT. (sixteen 6-bit
registers in total).
{D5~D0}: These bits are for general purpose not
volatile data storage or for storage of up to four different
wiper values. The contents of Data Register 0 are
automatically moved to the wiper counter register on
power-up.
Wiper Counter Register, (6-bit), volatile:
One 6-bit Wiper Counter Register for each EEPOT. (Four
6-bit registers in total.)
{D5~D0}: These bits specify the wiper position of the
respective EEPOT. The Wiper Counter Register is
loaded on power-up by the value in Data Register 0.
The contents of the WCR can be loaded from any of
the other Data Register or directly. The contents of the
WCR can be saved in a DR.
