Pin Assignments
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 potentiometer and pot register
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
X9421.
CHIP SELECT (CS)
When CS is HIGH, the X9421 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 X9421, 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.
