XRA1405 General Description

The XRA1405 is an 16-bit GPIO expander with an SPI interface. After power-up, the XRA1405 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled. In addition, the GPIOs on the XRA1405 can individually be controlled and configured. As outputs, the GPIOs can be output.
