3.2.4 Tool Reset Specifications

A tool reset is a hardware reset by the adapter to reset the entire system of the
microcontroller (including the BDSU module) on the user system. When both the
adapter power and microcontroller's user power are turned on, the tool reset is
canceled automatically to enable the microcontroller 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. Set the micorocontroller's user power from OFF to ON (power-on reset). The
reset remains in effect for about 16 to 70 ms after the microcontroller's user
power is supplied.
