XRA1403 - 16-Bit SPI GPIO Expander
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 output
