GPIO[12]
The GPIO[12] truth table is (for the abbreviation list please refer to
Table 53.
1. AUX2Enable or AUX2System bit =1 represent the case in which AUX2 is used as a regulator (system or
2. When Op2EnPlusPin = ‘1’ the GpioOutEnable[11] bit is forced to 0.
3. In all configurations in which GPIO[12] is enabled as output:
AUX2enable
AUX2syste
not system).
a) the GPIO[12] pin can be always used as an analog input to the ADC system (ADC function) by writing
b) the GPIO[12] pin can be always used as a digital input so its value can be always read through SPI
c) please note that GPIO[12] output is directly connected to StepCmd input for stepper driver and
d) the GPIO[12] pin is a rail to rail, back to back output supplied by V

interface (SPI_IN function);
therefore particular care must be taken in order to avoid wrong PWM signals when StepCmd is
selected for stepper driver (STEP_REQUEST function)
