GPIO[10]
The GPIO[10] truth table is (for the abbreviation list please refer to
Table 51.
1. The Op1EnMinusPin bit in the OpAmp1Ctrl register enables the connection of the positive input of Op1 to
2. The GPIO[10] pin is used by the system when firmware requires the ID read action
3. When Op1EnPlusPin = ‘1’ the GpioOutEnable[10] bit is forced to 0.
4. In all configurations in which GPIO[10] is enabled as output:
Op1EnPlusPin
GPIO[10] pin.
a) the GPIO[10] pin can be always used as an analog input to the ADC system (ADC function) by writing
b) the GPIO[10] pin can be always used as a digital input so its value can be always read through SPI
c) please note that GPIO[10] output is directly connected to ExtPWM2 input for bridge 1 or 2 and
d) the GPIO[10] pin is a rail to rail output supplied by V
its address in the A2DChannelX[4:0] in the A2DConfigX register and starting a conversion;
interface (SPI_IN function);
therefore particular care must be taken in order to avoid wrong PWM signals when ExtPWM2 is
selected for bridge 1 or 2;
