Complementary operating manual
Description
Routes the Reset output of the external watchdog supervisory
circuit to the reset input of the controller. This enables the
watchdog circuit to reset the controller in case of under voltage
or watchdog tripping. For normal operation this jumper must be
closed.
Causes the controller to enter the bootloader routines upon
system restart for firmware download. This disables the user
code from executing. For normal operation this jumper must be
open.
Routes the controller generated watchdog trigger signal to the
supervisory circuit. This enables the external watchdog logic. If
the jumper is left open the external watchdog logic will be
disabled. For normal operation this jumper must be closed.
