3.15 Melody/Alarm Generator (MLD)
from the MLDALM pin. Five kind of fixed cycles interrupt is generate by using 15-bit counter,
which is used for alarm generator.
TMP91C820A incorporates melody function and alarm function, both of which are output
Features are as follows.

able to invert by setting a value to a register.

(00E7hex). These bits are used when you want to operate LCDC and MELODY circuit
without low-frequency clock (XTIN, XTOUT). After reset these two bits set to 0 and low
clock is supplied each LCDC and MELODY circuit. If you write these bits to 1, TA3
(Generate by timer 3) is supplied each LCDC and MELODY circuit. In this case, you should
set 32 kHz timer 3 frequency. For detail, look AC specification characteristics.
• Melody generator
• Alarm generator
• Special mode
The melody function generates signals of any frequency (4 Hz to 5461 Hz) based on
By connecting a loud speaker outside, melody tone can easily sound.
The Alarm function generates eight kinds of alarm waveform having a modulation
By connecting a loud speaker outside, alarm tone can easily sound.
Five kind of fixed cycles (1 Hz, 2 Hz, 64 Hz, 512 Hz, 8192 Hz) interrupts be generated by
