PIN ASSIGNMENTS
PIN DESCRIPTIONS
Bus Interface Pins
SERIAL OUTPUT (SO)
SO is a 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
X9260.
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 (A1 - A0)
The address inputs are used to set the 4-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 X9260.
CHIP SELECT (CS)
When CS is HIGH, the X9260 is deselected and the
SO pin is at high impedance, and (unless an internal
write cycle is underway) the device will be in the
Pin
