    Using Different Pins to Control External BLE Power Amplifier


      Hi everyone!
      We are equipping PSoC 6 with an external power amplifier/low noise amplifier (PA/LNA) . As PSoC 6 documents say, there are three specific dedicated pins to control an external PA/LNA : P7.4 and P7.5 (RX_EN and TX_EN). However, in top design we digitally connected them to P0.0 and P0.1 . (we are not using an external 32768Hz crystal and BLE is run by ILO.)
      I am wondering whether this approach is acceptable or it might affect the quality of real-time audio data transfer over BLE.
