10. _RESET 9. EMVDD Caution The constants described in the circuit connection example are reference values. If you perform flash
programming aiming at mass production, thoroughly evaluate whether the specifications of the target device are satisfied.
Notes 1.The circuit enclosed by a dashed line is not required when only flash programming is performed.
2. Pull-up resistor is not required if the reset circuit on the target system contains no buffers and the reset signal is only generated via resistors or capacitors.
3.The drive power supply of TOOL0 is different depending on devices.Defer to user’s manual of device.
