B0 : TXGAIN0_CH0_FADECONT control
Initial value: 4C10h (+1.5dB)
When changing the step amount X, compute it using the following equation:
Equation: 10^ (X/20)*16384
Example: Making the step value +3 dB:
Initial value : 35D9h (−1.5 dB)
When changing the step amount X, compute it using the following equation:
Equation: 10^ (X/20)*16384
Example: Making the step value −3 dB:
10^ (−3/20)*16384 = 11599d = 2D4Fh
Maximum step value: –6.0 dB
Minimum step value: –0.1 dB
(Remarks) The step values of fade-in and fade-out can be set individually, but parameters that have been set will
become common among all gain controllers that enable fade-in/fad-out processing.
10^ (3/20)*16384 = 23143d = 5A67h
Maximum step value: +6.0 dB (data: 7FB2h)
Minimum step value: +0.1 dB (data: 40BEh)
1 : ON (Performs fade-in/out processing when changing TXGAIN0_CH0.)
0 : OFF
(data: 2013h)
(data: 3F44h)
