recv_pmeter2_ena : Enables the Receive Input Interface pmeter2 block when set
recv_pmeter3_ena : Enables the Receive Input Interface pmeter3 block when set
ssel_ recv_pmeter0(2:0) : Selects the sync source for the Receive Input Interface pmeter0 block

recv_pmeter0_sqr_sum(15:0) : The sqr_sum register controls the number of samples to accumulate for
a power measurement. Ia is (or Ia & Qa if complex mode is selected are) squared and
accumulated. Eight Ia samples (or eight sample pairs of Ia and Qa samples) equal to one
sqr_sum count. The accumulation interval is initiated when the sync is asserted and the
programmed (8*sync_delay+2) samples has expired or when the interval start time is
reached. When the (8*sqr_sum+1) sample time is reached, the accumulated powers are
made available for MPU access and an interrupt is generated.
