PWR_OP_I(1:0)
PWR_OP_Q(57:52)
PWR_OP_Q(57:0) – Power meter output for Q channel when it is configured in the Fine mode . This
represents power of Q channel when configured in the real mode. In the complex mode, this does not
contain any information. For a 12-bit output (as is the case in AFE722x), the lower eight bits will not
contain any information; so it is sufficient to read out PWR_OP_Q(57:8).
PWR_OP_I(57:0) – Power meter output for I channel when it is configured in the Fine real mode. This
represent the power of the I channel, and in the complex mode, it represents the complex power. For a
12-bit output (as is the case in AFE722x), the lower eight bits will not contain any information; so it is
sufficient to read out PWR_OP_I(57:8).
