PIN DESCRIPTIONS
The basic functions of each pin of the ML63187B, ML63189B 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.

Low-speed clock oscillation pins
An option for using crystal oscillation or RC
oscillation is chosen by the mask option.
If the crystal oscillation is chosen, a crystal
should be connected between XT0 and XT1,
and capacitor (CG) should be connected
between XT0 and VSS.
If the RC oscillation is chosen, external
oscillation resistor (ROSL) should be connected
between XT0 and XT1.
