16-bit I2C-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
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.
6.5 Power-on reset
When power is applied to VDD, an internal Power-On Reset (POR) holds the PCA9532 in
a reset condition until VDD has reached VPOR. At that point, the reset condition is released
and the PCA9532 registers are initialized to their default states, all the outputs in the
OFF state. Thereafter, VDD must be lowered below 0.2 V to reset the device.
6.6 External RESET
A reset can be accomplished by holding the RESET pin LOW for a minimum of tw(rst). The
PCA9532 registers and I2C-bus state machine will be held in their default states until the
RESET input is once again HIGH.
This input requires a pull-up resistor to VDD if no active connection is used.
