waveform is reversible by setting a value to a register.
by the free-run counter which is used for alarm generator.

The Alarm function generates 8 kinds of alarm waveform having a modulation
By connecting a loud speaker outside, Alarm tone can sound easily.
Five kinds of fixed cycle (1 Hz, 2 Hz, 64 Hz, 512 Hz, 8 kHz) interrupts are generate
At first, MELALMC<MELALM> have to be set as “0” in order to select alarm
