Description
Sets Control Register bits to logic low. The Dot Register contents are unaffected by the
Reset pin. (logic low = reset; logic high = normal operation).
Serial Data input for Dot or Control Register data. Data is entered on the rising edge of the
Clock input.
Serial Data output for Dot or Control Register data. This pin is used for cascading
multiple displays.
Clock input for writing Dot or Control Register data. When Chip Enable is logic low, data
is entered on the rising Clock edge.
Selects Dot Register (RS = logic low) or Control Register (RS = logic high) as the
destination for serial data entry. The logic level of RS is latched on the falling edge of
the Chip Enable input.
This input must be a logic low to write data to the display. When CE returns to logic
high and CLK is logic low, data is latched to either the LED output drivers or a Control
Register.
Selects either an internal or external display oscillator source. (SEL) (logic low = External
Display Oscillator; logic high = Internal Display Oscillator).
Output for the Internal Display Oscillator (SEL = logic high) or input for an External
Display Oscillator (SEL = logic low).
Blanks the display when logic high. May be modulated for brightness control.
Ground for LED drivers.
Ground for logic.
Positive supply for LED drivers.
Positive supply for logic.
