Serial Data Input
Serial Data Clock. The rising edge of the CLK signal is used to clock
data into and at the falling edge out of the AS1109 shift register. In error
mode, the rising edge of the CLK signal is used to switch error modes.
Serial Data Load. Data is transferred to the data register at the rising
edge of this pin.
Output Current Drivers. These pins are used as LED drivers or for
input sense for diagnostic modes.
Output Enable. The active-low pin OEN signal can always enable
output drivers to sink current independent of the AS1109 mode.
0 = Output drivers are enabled.
1 = Output drivers are disabled.
Serial Data Output. In normal mode SDO is clocked out 8.5 clock cycles
after SDI is clocked in.
In global error detection mode this pin indicates the occurrence of a
global error.
0 = Global error mode returned an error.
1 = No errors.
External Resistor Connection. This pin connects through the external
resistor (REXT) to GND, to setup the load current.
Positive Supply Voltage
