INTRV_CNT (4:0)
PWR_MTR_MODE
PWR_MTR_FINE
PWR_MTR_EN
INTRV_CNT(4:0) – Lower 4 bits of the 21 bit Interval count for the Power meter
PWR_MTR_EN – Enables the power meter. Common for fine and coarse power meters.
PWR_MTR_FINE – When cleared, configures the power meter in ‘Fine ‘ mode where it gives linear
output . When set, configures it in the coarse mode, where it gives output in the db scale.In coarse mode,
the
number
of
samples
over
which
power
is
computed
is
specified
in
the
PWR_MTR_COARSE_SAMPLES(2:0) in CONFIG82.
PWR_MTR_MODE – When cleared, configures the power meter in the real mode – Output I = I2, Output
Q = Q2. When set, configures it in complex mode – Output = I2 + Q2.
Register Name – CONFIG91 – Address 0x183, Default = 0x00 (Read Only)

PWR_OP_I(57:50)
PWR_OP_I(57:50) – Upper 8 bits of the Power meter output for I channel when it is configured in the Fine
mode. This represents power of I channel when configured in the real mode, and the complex power when
configured in the complex mode.
