CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Melody Generator)
Furthermore, 4 types of playing speed may be selected in
the S1C62N82 Series. The selection can be done through
the software and control is performed by writing data on
CLKC0 and CLKC1 registers of the controller. The data
written on the registers and the corresponding playing speed
are shown in Table 4.11.8. By writing "0" on CLKC0 and
CLKC1, normal speed tempo (i.e., tempo selected by mask
option) may be played. Playing at 8 times, 16 times and 32
times of the normal speed is useful for producing sound
effects for games and animal sounds.

Note Changing the playing speed is instantly accomplished by writing
data on CLKC0 and CLKC1 registers. When speed need not be
changed in the middle of a melody, write the playing speed data
upon completion of a melody playing, i.e., during rest.
