XRA1404 - 8-Bit SPI GPIO Expander
The XRA1404 is an 8-bit GPIO expander with an SPI interface.
After power-up, the XRA1404 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled.
In addition, the GPIOs on the XRA1404 can individually be controlled and configured.
As outputs, the GPIOs can be outputs
