Chapter 20 Melody Driver
20.3.2 Tempo Codes
A tempo code is set in the melody 0 tempo code register (MD0TEM).
Table 20-1 shows the correspondence between tempos (number of counts for one minute) and tempo codes.
The tempo when all the bits are set to "0" is equal to the shortest tone length (the tempo when the only M0TP0 bit is set
to "1").
