Function
Function
Ground pin for the A/D converter
Connect it to the system ground (0
V).
Connect all AVss pins to the system
ground (0 V) correctly.

Initialization-signal input pin
Function
Sets the ASE mode.
When a low-level signal is input to
this pin, the MCU enters ASE mode.
When a high-level signal is input,
MCU enters normal mode (MCU
operation mode or on-chip flash
memory programming mode).
Emulator-specific functions are
available in ASE mode. When no
signal is input, this pin is pulled up
internally.
If only normal mode will be used, pull
up the pin by connecting a resistor.
E10A emulator break input pin
Indicates that the E10A emulator has
entered its break mode.
