2.6.1 Supplying Target LSI V
DD
from EASE1000
EASE1000 has the pin (3.3VOUT) to 3.3 V/100 mA (max) as a target LSI operation power supply.
When this power supply is used, the flash writer, on-chip debug emulator’s application program download and
software breakpoint functions are available even when the power supply voltage of the target system is set to a value
outside the flash memory operation voltage range of the target LSI.

Note
When using the 3.3VOUT power supply of EASE1000, do not apply power of the target
system to the V

pin of the target LSI.
If both power supplies are connected, it may damage EASE 1000 or cause an electric shock or
fire.
