8-bit I 2 C-bus LED dimmer
6.3.6 LS0 to LS1 - LED selector registers
The LSn LED select registers determine the source of the LED data.
00 = output is set high-impedance (LED off; default)
01 = output is set LOW (LED on)
10 = output blinks at PWM0 rate
11 = output blinks at PWM1 rate

6.4 Pins used as GPIOs
LED 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 PCA9531 in
a reset condition until V DD has reached V POR . At that point, the reset condition is released
and the PCA9531 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.
6.6 External RESET
A reset can be accomplished by holding the RESET pin LOW for a minimum of t w(rst) . The
PCA9531 registers and I 2 C-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 V DD if no active connection is used.
