frequency of 4096 Hz determined by the low-speed clock (32.768 kHz). This waveform
is reversible by setting a value to a register.
192 Hz) by using a counter which is used for the alarm generator.
(Operation)
(Setting value of alarm pattern)
(Example program)
The alarm function generates eight kinds of alarm waveform having a modulation
The alarm tone can easily be heard by connecting an external loud speaker.
Five kinds of fixed cycle (interrupts can be generated 1 Hz, 2 Hz, 64 Hz, 512 Hz, 8
waveform to be output from MLDALMC. The “10” must be set on the MELALMC
<FC1:0> register, and clear internal counter. Alarm pattern must then be set on
the 8-bit register of ALM. If it is inverted output-data, set <ALMINV> as invert.

Setting Value for ALM Register
MELALMC<MELALM> must first be set as 0 in order to select the alarm
The following are examples of program, setting value of alarm pattern and
Then set the MELAMC<FC1:0> to “11” to start the free-run counter.
To stop the alarm output, write “00H” to the ALM register.
