22.12 GPIO[11]
The GPIO[11] truth table is (for the abbreviation list please refer to Ta ble 4 0).
Table 52. GPIO[11] truth table
EnOpl
(1)
1. The EnOp1 bit in the OpAmp1Ctrl register enables the operational amplifier 1.
GPIO[11] SPI bits

Mode[2] Mode[1] Mode[0]
1 X X X X OpAmp1 Out

2. When EnOp1 = ‘1’ the GpioOutEnable[11] bit is forced to 0.
0 0 X X X HiZ (SPI_IN)
01000SPI OUT

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
its address in the A2DChannelX[4:0] in the A2DConfigX register and starting a conversion;
b) the GPIO[11] pin can be always used as a digital input so its value can be always read through SPI
interface (SPI_IN function);
c) please note that GPIO[11] output is directly connected to ExtPWM4 input for bridge 3 or 4 and
therefore particular care must be taken in order to avoid wrong PWM signals when ExtPWM4 is
selected for bridge 3 or 4;
d) the GPIO[11] pin is a rail to rail output supplied by V
GPIO_SPI.
