GPIO[9]
The GPIO[9] truth table is (for the abbreviation list please refer to
Table 50.
1. The Op1EnPlusPin bit in the OpAmp1Ctrl register enables the connection of the positive input of Op1 to
2. The GPIO[9] pin is used by the system when firmware requires the ID read action
3. When Op1EnPlusPin = ‘1’ the GpioOutEnable[9] bit is forced to 0.
4. In all configurations in which GPIO[9] is enabled as output:
Op1EnPlusPin
GPIO[9] pin.
a)the GPIO[9] pin can be always used as an analog input to the ADC system (ADC function) by writing its
b) the GPIO[9] pin can be always used as a digital input so its value can be always read through SPI
c)please note that GPIO[9] output is directly connected to ExtPWM1 input for Bridge 1 or 2 and therefore
d)the GPIO[9] pin is a rail to rail output supplied by V
address in the A2DChannelX[4:0] in the A2DConfigX register and starting a conversion;
interface (SPI_IN function);
particular care must be taken in order to avoid wrong PWM signals when ExtPWM1 is selected for
bridge 1 or 2;
