GPIO[11]
The GPIO[11] truth table is (for the abbreviation list please refer to
Table 52.
1. The EnOp1 bit in the OpAmp1Ctrl register enables the operational amplifier 1.
2. When EnOp1 = ‘1’ the GpioOutEnable[11] bit is forced to 0.
3. In all configurations in which GPIO[11] is enabled as output:
a) the GPIO[11] pin can be always used as an analog input to the ADC system (ADC function) by writing
b) the GPIO[11] pin can be always used as a digital input so its value can be always read through SPI
c) please note that GPIO[11] output is directly connected to ExtPWM4 input for bridge 3 or 4 and
d) the GPIO[11] pin is a rail to rail output supplied by V
EnOpl
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 ExtPWM4 is
selected for bridge 3 or 4;
