OPERATION
68EVB912B32UM/D 3-45
RESET Reset Target MCU RESET
syntax:
RESET
The RESET command is used to reset the target system processor when operating in D-Bug12’s
POD mode. The target processor’s reset pin is held byte-erasable for approximately 2 mS.
When the reset line is released, BDM commands are sent to the target processor to place it in
active background mode. The target processor’s registers are initialized with the same values
used for the registers when operating in EVB mode.
The effects of the RESET command may be different from a user assertion of the target's
RESET* pin:
•
When the RESET command is issued, the host EVB controls the state of the target's
BKGD pin, placing the target processor in Special mode and active background
execution.
•
When a user assertion of the target's RESET* pin occurs, the target processor may
enter either Special or Normal mode, depending on the state of its BKGD pin.
D-Bug12 displays a message indicating that the target processor has been reset.
restrictions:
When operating in the EVB mode, the RESET command cannot be used. If the RESET
command is entered while in EVB mode, an error message is displayed and command execution
is terminated.
example:
S>RESET
Target Processor Has Been Reset
S>G 4000
R>RESET
Target Processor Has Been Reset
