2 GENERAL DESCRIPTION The XRA1403 is an 16-bit GPIO expander with an SPI interface.
After power-up, the XRA1403 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled.
In addition, the GPIOs on the XRA1403 can individually be controlled and configured.
As outputs, the GPIOs can be outputs that are high, low or in three-state mode.
The three-state mode feature is useful for applications where the power is removed from the remote devices, but they may still be connected to the GPIO expander.
As inputs, the internal pull-up resistors can be enabled or disabled and the input polarity ...
