PWM0 — PWM REGISTER 0
bit

The PWM0 register determines the duty cycle of BLINK0. The
outputs are LOW (LED off) when the count is less than the value in
PWM0 and HIGH when it is greater. If PWM0 is programmed with
00h, then the PWM0 output is always LOW.

The LSx LED select registers determine the source of the LED data.
00 = Output is set LOW (LED on)
01 = Output is set Hi-Z (LED off – default)
10 = Output blinks at PWM0 rate
11 = Output blinks at PWM1 rate
PINS USED AS GENERAL PURPOSE I/Os
LED pins not used to control LEDs can be used as general purpose
I/Os.
For use as input: Set LEDx to high-impedance (01) 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.
LED 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.
POWER-ON RESET
When power is applied to V
DD
, an internal Power-On Reset holds
the PCA9552 in a reset condition until V
DD
has reached V
POR
. At
this point, the reset condition is released and the PCA9552 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.
EXTERNAL RESET
A reset can be accomplished by holding the RESET pin LOW for a
minimum of t
W
. The PCA9552 registers and I
2
C state machine will
be held in their default state until the RESET input is once again
HIGH.
This input requires a pull-up resistor to V
DD
if no active connection is
used.
