C. Internal data memory for tone output time control (TGEN1_TIM_M0/TGEN1_TIM_M1)
D. Internal data memory for tone total gain control (TGEN1_RXGAIN_TOTAL/TGEN1_TXGAIN_TOTAL)
E. Internal data memory for TGEN1 fade control (TGEN1_FADE_CONT)
OKI Semiconductor
TGEN1 output time control 0 (TGEN1_TIM_M0)
TGEN1 output time control 1 (TGEN1_TIM_M1)
Compute the value using the following equation when changing the time durations:
Equation: T/0.125 (T is the time duration in milliseconds)
Example: When setting a time duration of 200 ms:
200/0.125 = 1600d = 0640h
Upper limit: 4095.875 ms (data: 7FFFh)
Lower limit: 0.125 ms
Note:
Setting a time duration of 0000h (0 ms) is prohibited.
TGEN1 RX-side tone total gain control (TGEN1_RXGAIN_TOTAL)
TGEN1 TX-side tone total gain control (TGEN1_TXGAIN_TOTAL)
The initial values will be 0 dB. Compute using the following equation when changing the output level.
Equation: 0080h × GAIN
Example: Decreasing the output level by 6 dB:
0080h × 0.5 = 0040h
Upper limit: +40 dB
Lower limit: −40 dB
Note:
The maximum amplitude should never exceed 3.17 dBm0.
Initial value : 0000h (stop)
Setting “0001h” in this data memory operates the fade-in/fade-out function of TGEN1 gain control.
Note:
When using this control function, set the fade-out time correctly.
Initial value: 0FA0h (500 ms)
Initial value: 0FA0h (500 ms)
Initial value: 0080h
Initial value: 0080h
0000h : Stops fade-in/fade-out
0001h : Operates fade-in/fade-out
: MUTE
