OKI Semiconductor
Initial value: 4C10h (+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:
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:
(Remarks) The step values can be set individually, but parameters set will become common to
TGEN1_RXGAIN_TOTAL and TGEN1_TXGAIN_TOTAL. Also, the operation control parameters will
become common to TGEN1_RXGAIN_TOTAL and TGEN1_TXGAIN_TOTAL.
TGEN1_EXFLAG is set to “1” while the tone generator 1 is operating. (Initial value = “0”: Generator stopped)
10^ (3/20)*16384 = 23143d = 5A67h
Maximum step value: +6.0 dB
Minimum step value: +0.1 dB
10^ (−3/20)*16384 = 11599d = 2D4Fh
Maximum step value: −6.0 dB
Minimum step value: –0.1 dB
