3.15 Melody/Alarm Generator (MLD)
from the MLDALM pin. Five kinds of fixed cycle interrupt are generated using a 15-bit counter
for use as the alarm generator.
1)
2)
The TMP92CH21 contains a melody function and alarm function, both of which are output
The features are as follows.
Melody generator
low-speed clock (32.768 kHz), and outputs the signals from the MLDALM pin.
Alarm generator
frequency (4096 Hz) determined by the low-speed clock (32.768 kHz). This waveform can be
inverted by setting a value to a register.
Hz) by using a counter which is used for the alarm generator.
The Melody function generates signals of any frequency (4 Hz to 5461 Hz) based on a
The melody tone can easily be heard by connecting an external loudspeaker.
The alarm function generates eight kinds of alarm waveform having a modulation
The alarm tone can easily be heard by connecting an external loudspeaker.
Five kinds of fixed cycle interrupts are generated (1 Hz, 2 Hz, 64 Hz, 512 Hz, and 8192
