or analog control register is essentially a write to a
static RAM. The response of the wiper to this action
will be delayed tSTPWV. A transfer from the Wiper
Counter Register current wiper position to a data reg-
ister is a write to nonvolatile memory and takes a mini-
mum of tWR to complete. The transfer can occur
between one of the two potentiometers or one of the
two voltage comparators and one of its associated
registers; or it may occur globally, wherein the transfer
occurs between both of the potentiometers and volt-
age comparators and one of their associated registers.
Four instructions require a three-byte sequence to com-
plete. The basic sequence is illustrated in Figure 4.
These instructions transfer data between the host and
the X9448; either between the host and one of the data
registers or directly between the host and the wiper
counter and analog control registers. These instructions
are: read wiper counter register or analog control regis-
ter, read the current wiper position of the selected pot or
the comparator control bits, Write wiper counter register
or analog control register, i.e. change current wiper
position of the selected pot or control the voltage com-
parator; read data register, read the contents of the
selected nonvolatile register; write data register, write a
new value to the selected data register. The bit struc-
tures of the instructions are shown in Figure 6.
The increment/decrement command is different from
the other commands. Once the command is issued
and the X9448 has responded with an acknowledge,
the master can clock the selected wiper up and/or
down in one segment steps; thereby, providing a fine
tuning capability to the host. For each SCL clock pulse
(tHIGH) while SDA is HIGH, the selected wiper will
move one resistor segment towards the VH terminal.
Similarly, for each SCL clock pulse while SDA is LOW,
the selected wiper will move one resistor segment
towards the VL terminal. A detailed illustration of the
sequence for this operation is shown in Figure 5.
