The output port register sets the outgoing logic levels of
the I/O ports, defined as outputs by the configuration
register. Bit values in this register have no effect on I/O pins
defined as inputs. Reads from the output port register reflect
the value that is in the flipflop controlling the output, not
the actual I/O pin value.
The polarity inversion register allows the user to invert the
polarity of the input port register data. If a bit in this register
is set (“1”) the corresponding input port data is inverted. If
a bit in the polarity inversion register is cleared (“0”), the
original input port polarity is retained.
The configuration register sets the directions of the ports.
Set the bit in the configuration register to enable the
corresponding port pin as an input with a high impedance
output driver. If a bit in this register is cleared, the
corresponding port pin is enabled as an output. At
powerup, the I/Os are configured as inputs with a weak
pullup resistor to VCC.
Data is transmitted to the CAT9534’s registers using the
The CAT9534’s registers are read according to the timing
command byte has been sent, the register which was
addressed will continue to be accessed by reads until a new
command byte will be sent.
