Operational Description
XTIN
(1) Operational overview
Based on the low-speed clock (32.768 kHz), clock waveforms at any frequency from
4 Hz to 5461 Hz can be generated and output from the MLDALM pin.
The melody frequency is calculated as below.
By connecting buzzer etc outside, melody sounds can easily be played.
