PIN DESCRIPTIONS
Host Interface Pins
Serial Output (SO)
SO is a push/pull serial data output pin. During a read
cycle, data is shifted out on this pin. Data is clocked
out by the falling edge of the serial clock.
Serial Input
SI is the serial data input pin. All opcodes, byte
addresses and data to be written to the pots and pot
registers are input on this pin. Data is latched by the
rising edge of the serial clock.
Serial Clock (SCK)
The SCK input is used to clock data into and out of the
X9401.
Chip Select (CS)
When CS is HIGH, the X9401 is deselected and the
SO pin is at high impedance, and (unless an internal
write cycle is underway) the device will be in the
standby state. CS LOW enables the X9401, placing it
in the active power mode. It should be noted that after
a power-up, a HIGH to LOW transition on CS is
required prior to the start of any operation.
Hold (HOLD)
HOLD is used in conjunction with the CS pin to select the
device. Once the part is selected and a serial sequence
is underway, HOLD may be used to pause the serial
communication with the controller without resetting the
serial sequence. To pause, HOLD must be brought LOW
while SCK is LOW. To resume communication, HOLD is
brought HIGH, again while SCK is LOW. If the pause
feature is not used, HOLD should be held HIGH at all
times.
Device Address (A
0
-
A
1
)
The address inputs are used to set the least significant 2
bits of the 8-bit slave address. A match in the slave address
serial data stream must be made with the address
input in order to initiate communication with the
X9401. A maximum of 4 devices may occupy the SPI
serial bus.

the Wiper Counter Registers.
