PCA9533
4-bit I 2 C-bus LED dimmer
6.4 Pins used as GPIOs
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
INPUT 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.
6.5 Power-on reset
When power is applied to V DD , an internal Power-On Reset (POR) holds the PCA9533 in
a reset condition until V DD has reached V POR . At that point, the reset condition is released
and the PCA9533 registers are initialized to their default states, all the outputs in the
OFF state. Thereafter, V DD must be lowered below 0.2 V to reset the device.
