PIN DESCRIPTIONS
The basic functions of each pin of the ML63512/63514 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.
For pin, "TB" denotes a 48-pin flat package (48TQFP), and "TP" a 64-pin flat package (64TQFP).

Description
Positive power supply
Negative power supply
Positive power supply pin for external interface (PORT8 supply)
Positive power supply pin for internal logic (internally generated).
A capacitor Cl (0.1 mF) should be connected between this pin and VSS.
Voltage multiplier pin for power supply backup (internally generated).
A capacitor Ch (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.
Input pins for testing.
A pull-up resistor is internally connected to these pins.
Reset input pin.
Setting this pin to "L" level puts this device into a reset state.
Then, setting this pin to "H" level starts executing an instruction
from address 0000H.
An internal or external pull-up resistor is selected by mask option.

Low-speed clock oscillation pins.
Crystal oscillation or RC oscillation is selected by the mask option.
If crystal oscillation is selected, connect a crystal between XT0 and
XT1, and connect capacitor (CG) between XT0 and VSS.
If RC oscillation is selected, connect external oscillation resistor
(RCRL) between XT0 and XT1.
High-speed clock oscillation pins.
Ceramic oscillation or RC oscillation is selected by the mask option.
If ceramic oscillation is selected, connect a ceramic resonator
between OSC0 and OSC1, and connect capacitor (CL0, CL1) between
OSC0 and VSS, OSC1 and VSS.
If RC oscillation is selected, connect external oscillation resistor
(RCRH) between OSC0 and OSC1.
