Pin Descriptions
1.7.1 Descriptions of the Basic Functions of Each Pin
The basic functions of each pin of the ML63611 are listed in Table 1-3. Use of a slash (“/”) in a pin name
indicates that the pin has a secondary function. See Table 1-4 for the secondary functions.
In the I/O column, “—” indicates a power supply pin, “I” indicates an input pin, “O” indicates an output pin, and
“I/O” indicates an input/output pin.

High-speed clock oscillation pins:
Ceramic oscillation or RC oscillation is selected by the
software. In the OPTION A and OPTION B, only RC
oscillation is available.
If ceramic oscillation is selected, connect a ceramic
resonator between OSC0 and OSC1, and connect
capacitor (C
L0
, C
L1
) between OSC0 and V
SS
and between
OSC1 and V
SS
.
If RC oscillation is selected, connect external oscillation
resistor (R
