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.

Indicates that the E10A emulator has
entered its break mode.
