GPIO[10]

The GPIO[10] truth table is (for the abbreviation list please refer to Table 40).

Table 51.

GPIO[10] truth table

Op1EnPlusPin(1)

The Op1EnMinusPin bit in the OpAmp1Ctrl register enables the connection of the positive input of Op1 to

GPIO[10] pin.

GPIO[10] SPI bits

Function (2)

The GPIO[10] pin is used by the system when firmware requires the ID read action (Chapter 25)

(3)

When Op1EnPlusPin = ‘1’ the GpioOutEnable[10] bit is forced to 0.

SPI OUT

(4)

In all configurations in which GPIO[10] is enabled as output:

a) the GPIO[10] pin can be always used as an analog input to the ADC system (ADC function) by writing

its address in the A2DChannelX[4:0] in the A2DConfigX register and starting a conversion;

b) the GPIO[10] pin can be always used as a digital input so its value can be always read through SPI

interface (SPI_IN function);

please note that GPIO[10] output is directly connected to ExtPWM2 input for bridge 1 or 2 and

therefore particular care must be taken in order to avoid wrong PWM signals when ExtPWM2 is

selected for bridge 1 or 2;

d) the GPIO[10] pin is a rail to rail output supplied by VGPIO_SPI.
