Note:
DEBUG Mode
The operating characteristics of the devices in DEBUG Mode are:
•
•
•
•
•
Entering DEBUG Mode
The operating characteristics of the devices entering DEBUG Mode are:
•
•
Holding the DBG pin Low for an additional 5000 (minimum) clock cycles after reset (making
sure to account for any specified frequency error if using an internal oscillator) prevents a
false interpretation of an Autobaud sequence (see the
section on page 183).
RS-232 TX
RS-232 RX
The eZ8 CPU fetch unit stops, idling the eZ8 CPU, unless directed by the OCD to ex-
ecute specific instructions
The system clock operates unless in STOP Mode
All enabled on-chip peripherals operate unless 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) in-
struction
If the DBG pin is held Low during the final clock cycle of system reset, the part enters
DEBUG Mode immediately (20-/28-pin products only)
