0 GENERAL DESCRIPTION The XRA1200/1200P is an 8-bit GPIO expander with an I2C/SMBus interface.
After power-up, the XRA1200 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled.
The XRA1200P have the internal pull-up resistors enabled upon power-up in case it is necessary for the inputs to be in a known state.
In addition, the GPIOs on the XRA1200/1200P 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...
