When in other than the sleep state: Functions
as a software reset pin. Pin for resetting from
the MCU
When in the sleep state: Functions as a sleep
release pin. This pin is enabled only when
RESETN = 1.
2 XIN H I

10 MHz crystal connection pin 2
Left open when the XIN pin is configured as
an external clock input pin.
39 CLKOUT L
IO
System clock output pin. Clock supply to
MCU is possible. Mode setting function
6 EXTCLK I

1.4.5 Handling of Unused Pins
See below for handling of unused pins. Such handling as leads to impair the basic operation of the
ML7065-033 are not included.
Handling of Unused Pins
Symbol
Recommended pin handling
XOUT
Open (when XIN is configured as an external clock input pin).
MODE1
Connect to GND.
MODE2
Connect to GND.
MODE3
Connect to GND.
CLKOUT Open.
EXTCLK
Connect to GND.
SRESETN
Connect to VDD.
N.C. Open.
Note: If any input pin is left open, the supply current may become excessive. Therefore, it is recommended that
unused input ports and I/O ports be configured as input with pull-up resistor/input with pull-down resistor.
