Series
Positive power terminal
(1) If the External Clock Input mode is selected by low (0) level input to the CKS2
terminal:
One of the following square waves must be entered as the reference signal source
to this terminal:
32.768 kHz, 38.4 kHz, 76.8 kHz, or 153.6 kHz
This selection range can be changed using the mask option as follows:
32.768 kHz, 38.4 kHz, 76.8 kHz, or 96.0 kHz
In the Standby mode (that is, when the MT terminal is low and no music is played),
all internal circuits do not operate even when an external clock is entered in this
terminal. This terminal may be opened (floating). While in the Operation mode (that
is, when a music is played or the high level signal is entered in the MT terminal), this
terminal must not be open (or not floating).
If this terminal is fixed to low (0) or high (1) level, the internal circuits change to the
Operation mode even when the low level signal is entered in the MT terminal.
However, these circuits are held and do not operate until the clock is entered.
Therefore, if the low (0) level signal is entered in the MT terminal, the system is not
returned to the Standby mode. The clock signal must be entered.
(2) If the high (1) level signal is entered in the CKS2 terminal and if the built-in RC
oscillator is used as the reference signal source:
This terminal functions as the IC test output terminal and it outputs the drive voltage
of the RC oscillator circuit. The terminal must be open, and no external voltage must
be supplied to it.
One of the following four external clocks and the reference signal source of the following
built-in RC oscillator frequencies can be selected by the combination of signals of these
three terminals.
Do not change the input signal level during Operation mode as each terminal does not
has the chattering protect circuit.
Also, the low (0) or high (1) level signal must be entered as these three terminals do not
have the pull-down or pull-up resistor.
If the External Clock Input mode is selected, the built-in RC oscillator circuit and the
voltage regulator circuit to drive it are in the Standby mode.
The music tempo does not change when any of the above five frequencies is used.
However, the tone frequency is high for 32.768/38.4 at 32.768 kHz, and it is low for 32.0/
38.4 at 96.0 kHz.
During RC oscillation, the music tempo and tone frequency change in proportion to the
shifted oscillation frequency.
