+ * @details
+ *
+ * The rf channel table is used to program internal hardware register for different 15.4 rf channels.
+ * It has 16 entries corresponding to 16 15.4 channels.
+ * Entry 1 <-> Channel 11
+ * ...
+ * Entry 16 <-> Channel 26
+ *
+ * Each entry is compound of 4 items.
+ * Item 0: Rx Frequency integer divide portion
+ * Item 1: Rx Frequency fractional divide portion
+ * Item 2: Tx Frequency integer divide portion
+ * Item 3: Tx Frequency fractional divide portion
+ *
+ * The tx power table is used to program internal hardware register for different 15.4 tx power levels.
+ * It has 43 entries corresponding to tx power levels from -32dBm to +10dBm.
+ * Entry 1 <-> -32dB
+ * Entry 2 <-> -31dB
+ * ...
+ * Entry 2 <-> 9dB
+ * Entry 43 <-> +10dB
+ *
+ * Each entry is compound of 1 byte.
