Serial Data Input
Serial Data Clock.
The rising edge of the CLK signal is used to clock data
into and out of the AS1110 shift register. In error mode, the rising edge of the
CLK signal is used to switch error modes.
Serial Data Load
Output Current Drivers.
These pins are used as LED drivers or for input
sense for diagnostic modes. Data is transferred to the data register at the
rising edge of these pins.
Output Enable.
The active-low pin OEN signal can always enable output
drivers to sink current independent of the AS1110 mode.
0 = Output drivers are enabled.
1 = Output drivers are disabled.
Serial Data Output.
In normal mode SDO is latched out 8.5 clock cycles
after SDI is latched 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 (R
EXT
) to GND, to setup the load current.
