PIN CONFIGURATION
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
X9261.
