Tone Generator Control Output Level
(Condition: EV3 = 0 dB)
: Operational,
: Power down, H-Z : High-impedance, L: L-level fixed, SGC: SGC fixed
Note: When the TONC pin signal is L-level, the tone generator circuit counters will be reset. When a dual tone is
generated at the time of reset, the initial phase settings for tone
and tone
will be in phase.
Example: When Tone (1), Tone (2) are at the same frequency:
