DEBUG Mode
The operating characteristics of the devices in DEBUG mode are:
•
•
•
•
•
Entering DEBUG Mode
•
•
Exiting DEBUG Mode
The device exits DEBUG mode following any of these operations:
•
•
•
•
RS-232 TX
RS-232 RX
The eZ8 CPU fetch unit stops, idling the eZ8 CPU, unless directed by the OCD to execute
specific instructions.
The system clock operates, unless the device is in STOP mode.
All enabled on-chip peripherals operate, unless the device is in STOP mode.
Automatically exits HALT mode.
Constantly refreshes the Watchdog Timer, if enabled.
The device enters DEBUG mode after the eZ8 CPU executes a BRK (Breakpoint)
instruction
If the DBG pin is held low during the most recent clock cycle of system reset, the device
enters DEBUG mode on exiting system reset.
