IP175A LF
Preliminary Data Sheet
4.8
Initial value set by LED pins
Most configuration pins are shared with LED pin in IP175A LF. These multi-function pins are input during
reset period and are LED output after reset. IP175A LF reads initial value via pins during the reset period.
An initial value is set to 1 (0) by connecting a pin to vcc (gnd) through a 10k
Ω (1kΩ) resistor as shown on
the following figure.
The application circuit is shown below.
