Header, W2 Jumper header W2 controls the path of a target reset. The diagram here
shows the factory configuration: The fabricated jumper in the EVS
position enables the HC05EVS to control resets when you press the
user or master reset switch.
Alternatively, you can enable the target system to reset the H05EVS. To
do so:
• Reposition the M68EM05P18 W2 jumper to the TARGET position,
and
• Insert a fabricated jumper into the HC05EVS platform board
header J3.
• Provide RESET signal to connector J2 pin 2 (T_RST*)
