without low frequency clock (XTIN, XTOUT). After reset these two bits set to 0 and low
clock is supplied each LCDD and MELODY circuit. If you write these bits to 1, TA3
(Generate by timer 3) is supplied each LCDD and MELODY circuit. In this case, you should
set 32 kHz timer 3 frequency. For detail, look AC specification characteristics.
The Melody function generates signals of any frequency (4 Hz to 5461 Hz) based on
