PIN DESCRIPTIONS
The basic functions of each pin of the MSM63184B are described in Table 1.
A symbol with a slash (/) denotes a pin that has a secondary function.
Refer to Table 2 for secondary functions.
For type, "—" denotes a power supply pin, "I" an input pin, "O" an output pin, and "I/O" an input-
output pin.

Description
Positive power supply
Negative power supply
Power supply pins for LCD bias (internally generated).
Capacitors (0.1
mF) should be connected between these pins and
VSS.
Capacitor connection pins for LCD bias generation.
A capacitor (0.1
mF) should be connected between C1 and C2.
Positive power supply pin for external interface
(power supply for input, output, and input-output ports)
Positive power supply pin for internal logic (internally generated).
A capacitor (0.1
mF) should be connected between this pin and VSS.
Voltage multiplier pin for power supply backup (internally generated)
A capacitor (1.0
mF) should be connected between this pin and VSS.
Pins to connect a capacitor for voltage multiplier.
A capacitor (1.0
mF) should be connected between CB1 and CB2.
Low-speed clock oscillation pins.
A 32.768 kHz crystal should be connected between XT0 and XT1,
and CG (5 to 25 pF) should be connected between XT0 and VSS.
High-speed clock oscillation pins.
A ceramic resonator and capacitors (CL0, CL1) or external
oscillation resistor (ROS) should be connected to these pins.
Input pins for testing.
A pull-down resistor is internally connected to these pins.
The user cannot use these pins.
Reset input pin.
Setting this pin to "H" level puts this device into a reset state.
Then, setting this pin to "L" level starts executing an instruction
from address 0000H.
A pull-down resistor is internally connected to this pin.
Buzzer output pin (non-inverted output)
Buzzer output pin (inverted output)
