■ Tool reset specifications
A tool reset is a hardware reset by the adapter to reset the entire system of the MCU (including the
BDSU module) on the user system.
When both of the adapter power and MCU’s user power are turned on, the tool reset is canceled au-
tomatically to enable the MCU to be evaluated.
The following shows how to generate a tool reset and how long it remains in effect.
• Tool reset generation methods and reset “L” pulse width
1. Turn the MCU user power from “OFF” to “ON” (power-on reset).
2. Turn the adapter power from “OFF” to “ON” (by unplugging and plugging the USB cable).
If an uncontrollable malfunction occurs in the user system and adapter that cannot be recovered using
tool reset generation method 1, execute tool reset generation method 2.
The reset remains in effect for about 16ms to 70ms after the MCU user power is supplied.
The reset remains in effect for about 32ms to 140ms after the adapter power is supplied.
