// Typically, the RF switch on SX126x boards is controlled by two signals, which are negations of each other (switched RFIO
// paths). The negation is usually performed in hardware, or (suboptimal design) TXEN and RXEN are the two inputs to this style of
// RF switch. On some boards, there is no hardware negation between CTRL and ¬CTRL, but CTRL is internally connected to DIO2, and
// DIO2's switching is done by the SX126X itself, so the MCU can't control ¬CTRL at exactly the same time. One solution would be
// to set ¬CTRL as SX126X_TXEN or SX126X_RXEN, but they may already be used for another purpose, such as controlling another
// PA/LNA. Keeping ¬CTRL high seems to work, as long CTRL=1, ¬CTRL=1 has the opposite and stable RF path effect as CTRL=0 and
// ¬CTRL=1, this depends on the RF switch, but it seems this usually works. Better hardware design, which is done most the time,
// means this workaround is not necessary.
