+ * After reboot default CADU bitrate is always set to 100 kbps (results in downlink rate
+ * of 200 kbps due to convolutional code added by syrlinks transceiver). The IP core handler exposes
+ * a parameter to enable the priority selection mode for the PTME core.
+ *
+ * If the transmitter is on, the selection mode will be enabled when the transmitter goes off.
+ * If the transmitter is off, the update of the PTME will be done immediately on a parameter update.
+ * This is done because changing this parameter requires a reset of the PTME core to avoid bugs
+ * while the transmitter is enabled.
