Tone Output Waveform
The D4 data bit at address 1010, 1100 may be used to select either sine-wave or trapezoidal waveforms for tone
output.
Tone Output Control
Tone output may be controlled by address and through the external tone control input pin TONC. In addition, the
tone control offers a choice of sine or trapezoidal waveforms.
LED Output Controls
Output from the LED output pins can be controlled by the TONC signal and the address 1110 data bit D
2
. When
the TONC signal is H-level, and the address 1110 data bit D
2
value is L-level, the output level will be high. Output
levels are CMOS levels.
