GPIO[5]
The GPIO[5] truth table is (for the abbreviation list please refer to
Table 46.
1. Master bit is at logic level “1” when
2. This bit is at logic level “1” if AUX1 regulator is a system regulator but its power stage is externally realized
3. In all configurations in which GPIO[5] is enabled as output:
Master
(and therefore the regulation loop is not used to drive bridge 3). In this case Vloop1IsSys bit will be at logic
level “1”, while Vloop1OnMtr3SideA and Vloop1OnMtr3SideB bits will be at logic level “0” in
CoreConfigReg register.
a) the GPIO[5] pin can be always used as an analog input to the ADC system (ADC function) by writing its
b) the GPIO[5] pin can be always used as a digital input so its value can be always read through SPI
c) the GPIO[5] pin is a rail to rail, back to back output supplied by V
