TMS320F28026F: adc number for foc drive

Part Number: TMS320F28026F

The TMS320F28026F product appears to be foc supported. but it has only one adc unit. But isn't a minimum of 2 adc and 3 pins required for foc (3 pins for simultaneous reading of two phases and changing phases)?

    It's better to implement simultaneous current sampling for high-end motor drive, but it's not must have for most of motor drives with InstaSPIN-FOC since the ADC of the TMS320F28026F  is fast enough and the delay between the three-phase current sensing doesn't have any significant impact on motor drive performance with InstaSPIN-FOC.
