typedef enum
{
    /* 2-FSK. Frequency deviations: {-fdev, +fdev} */
    FSK_MOD_ORD_2FSK = 0,

} DRV_RF215_FSK_MOD_ORD;

Defines the available FSK modulation orders.

This data type defines the list of available modulation orders for the RF215 FSK PHY.

The interpretation of modulation index for 4-FSK is slightly different to 802.15.4 specification. 4-FSK and modIdx=0.33 (in 802.15.4) is equivalent to 4-FSK and modIdx=1.0 (in RF215).

For 4-FSK, the RF215 has the following restriction: modIdx >= 1.0.
