Logic
System
RESET_N
I
Reset input pin. When this pin is set to a “L” level, system reset mode is
set and the internal section is initialized. When this pin is set to a “H” level
subsequently, program execution starts. A pull-up resistor is internally
connected.
Negative
XT0
I
XT1
O
Crystal connection pin for low-speed clock.
A 32.768 kHz crystal oscillator (see measuring circuit 1) is connected to
this pin. Capacitors CDL and CGL are connected across this pin and VSS
as required. ML610Q415 does not have the crystal oscillation function, but
connect XT0 to VSS and non-connect XT1 on ML610Q415.
OSC0
I
High-speed external clock input pin. This pin is used as the secondary
function of the P10.
Secondary
LSCLK
O
Low-speed clock output pin. This pin is used as the secondary function of
the P20 pin.
Secondary
OUTCLK
O
High-speed clock output pin. This pin is used as the secondary function of
the P21 pin.
Secondary
General-purpose input port
P00-P03
I
General-purpose input port.
Since these pins have secondary functions, the pins cannot be used as a
port when the secondary functions are used.
Primary
Positive
P10-P11
I
General-purpose input port.
Since these pins have secondary functions, the pins cannot be used as a
port when the secondary functions are used.
Primary
Positive
General-purpose output port
P20-P22
O
General-purpose output port.
Since these pins have secondary functions, the pins cannot be used as a
port when the secondary functions are used.
Primary
Positive
General-purpose input/output port
P30-P35
I/O
General-purpose input/output port.
Since these pins have secondary functions, the pins cannot be used as a
port when the secondary functions are used.
Primary
Positive
P40-P47
I/O
General-purpose input/output port.
Since these pins have secondary functions, the pins cannot be used as a
port when the secondary functions are used.
Primary
Positive
PA0-PA7
I/O General-purpose input/output port.
These pins are for the ML610Q411 and ML610Q415, but are not provided
in the ML610Q412.
