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 on the falling edge
of the serial clock.
SERIAL INPUT (SI)
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
X9110.
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 (A0)
The address input is used to set the 8-bit slave address. A
match in the slave address serial data stream A0 must be
made with the address input (A0) in order to initiate
communication with the X9110.
CHIP SELECT (CS)
When CS is HIGH, the X9110 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 X9110, 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.
HARDWARE WRITE PROTECT INPUT (WP)
The WP pin when LOW prevents nonvolatile writes to the
Data Registers.
