Note: 1. Under the RC oscillation mode. When the supply voltage drops below the voltage being generated the

internal constant voltage circuit, the RC oscillation frequency goes down below the prescribed level to

reduce the tempo and to bring down the pitch corresponding to the downward deviation of the oscillation

frequency. Other circuits function normally under the prescribed specifications.

2. This value is a reference value. Because current consumption varies depending on the programmed pitch,

tempo, used notes and address location with each ROM.
