GPIO[8]
The GPIO[8] truth table is (for the abbreviation list please refer to
Table 49.
1. The EnDAC bit in the CurrDacCtrl register enables the Current DAC
2. This pin is 5 volt input tolerant.
3. When EnDAC = ‘1’ the GpioOutEnable[8] bit is forced to 0. The current DAC circuit is directly connected to
4. The GPIO[8] pin can be always used as a digital input so its value can be always read through SPI
GPIO[8] pin so as soon as it is enabled it will sink current from pin.
interface (SPI_IN function). To avoid affecting the precision of CurrDAC when this is used to sink very low
currents, it is necessary to enable the digital input functionality of GPIO[8]. Therefore to read their values
through SPI interface (SPI_IN function), it is necessary to enable the EnGpio8DigIn bit in the CurrDacCtrl
register.
