Product data sheet
6.3.5 PWM1 - Pulse Width Modulation 1
6.3.6 LS0 - LED selector
6.4 Pins used as GPIOs
6.5 Power-on reset
The PWM1 register determines the duty cycle of BLINK1. The outputs are LOW (LED on)
when the count is less than the value in PWM1 and HIGH (LED off) when it is greater.
If PWM1 is programmed with 00h, then the PWM1 output is always HIGH (LED off).
The duty cycle of BLINK1 = PWM1 / 256.
Table 8.
The LS0 LED select register determines the source of the LED data.
Table 9.
Legend: * default value.
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 LS0. 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 PCA9530 registers are initialized to their default states, all the outputs in the
OFF state. Thereafter, V
