Description
IO Power supply pin
Connect all the VDD _IO pins.*
Core Power supply pin
Connect all the VDD _CORE pins.*
USB Power supply pin (Vbus input pin)
GND pin
Connect all the GND pins to GND.*
Analog reference voltage pin (Connect to the VDD pin when A/D converter
is not used.)
Analog GND pin (Connect to the GND pin when A/D converter is not
used.)
Sub-clock oscillation input pin
Connect to a crystal of f = 32.768 kHz.
Sub-clock oscillation output pin
Connect to a crystal of f = 32.768 kHz.
The clock output is opposite in phase to XT0.
Main clock oscillation input pin
Connect to a crystal or ceramic oscillator.
When an external clock is used, this pin is configured to be clock input.
Main clock oscillation output pin
Connect to a crystal or ceramic oscillator.
The clock output is opposite in phase to OSC0.
Leave this pin unconnected when an external clock is used.
D+ pin
D– pin
External control output pin
Reset input pin
Non-maskable interrupt input pin
Test pin
Connect to the GND pin for normal operation.
Test pin
Connect to the GND pin for normal operation.
Flash ROM programming mode input pin
When the FLAMOD pin is set to “L”, the device enters a programming
mode.
Connect to the VDD_IO pin when using as normal operation.
External program memory access input pin
When the EA pin is enabled (low level), the internal program memory is
masked and the CPU executes the program code in external program
memory through all address space.
* Connect all VDD_IO pins, all VDD_CORE pins and all GND pins.
If a device has one or more VDD_IO, VDD_CORE, or GND pins to which the power supply or the ground
potential is not connected, the family devices are not guaranteed to have normal operations.
