XRA1203 General Description

The XRA1203 is a 16-bit GPIO expander with an I2C/ SMBus interface. After power-up, the XRA1203 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled. In addition, the GPIOs on the XRA1203 can individually be controlled and configured. As outputs, the GPIOs can be .
