Bit[15:12] = 0x00	Read spectrum
Bit[15:12] = 0x01	Read MCS amplitude spectrum
Bit[15:12] = 0x02	Read spectrum buffer and unlock buffer
Bit[15:12] = 0x03	Read spectrum buffer and lock buffer
Bit[15:12] = 0x07	Read MCS amplitude spectrum buffer and lock buffer
38 Read out buffer state
Bit[15] = 1	Buffer filled
Bit[14] = 1	Buffer overrun
