85 / 104 page 3.62.8 ADC STATUS REGISTERS 3.63 GPIO TPS658620 Advanced Power Management Unit www.ti.com SLVS993 – OCTOBER 2009 The ADC conversion status for the timing engine is available in the ADC0_INT register. The ADC0_INT register is read-only. Reading the ADC0_INT register clears the ADC0INT bit in the STAT4 register (ADC0INT=0). Table 3-69.

When the GPIO is not configured the pull-down current source (2.5uA typ) is connected to the GPIOn pin. When configured as an input the GPIO can be set as inverting or non-inverting via bits GPIOnINV in the GPIOSET2 register. When configured as an output, the GPIO output level is defined by bits GPIOnOUT in the GPIOSET2 register. Table 3-70.
