Product data sheet
6.4 Pins used as GPIOs
6.5 Power-on reset
6.6 External RESET
LEDn pins not used to control LEDs can be used as General Purpose I/Os (GPIOs).
For use as input, set LEDn to high-impedance (00) and then read the pin state via the
INPUT0 or INPUT1 register.
For use as output, connect external pull-up resistor to the pin and size it according to the
DC recommended operating characteristics. LEDn output pin is HIGH when the output is
programmed as high-impedance, and LOW when the output is programmed LOW through
the ‘LED selector’ register. The output can be pulse-width controlled when PWM0 or
PWM1 are used.
When power is applied to V
a reset condition until V
and the PCA9532 registers are initialized to their default states, all the outputs in the
OFF state. Thereafter, V
A reset can be accomplished by holding the RESET pin LOW for a minimum of t
PCA9532 registers and I
RESET input is once again HIGH.
This input requires a pull-up resistor to V
