OCD Unlock Sequence (8-Pin Devices Only)
Because of pin-sharing on the 8-pin device, an unlock sequence must be performed to
access the DBG pin. If this sequence is not completed during a system reset, then the PA0/
DBG pin functions only as a GPIO pin.
The following sequence unlocks the DBG pin:
1. Hold PA2/RESET Low.
2. Wait 5 ms for the internal reset sequence to complete.
3. Send the following bytes serially to the debug pin:
DBG
80H (autobaud)
DBG
EBH
DBG
5AH
DBG
70H
DBG
CDH (32-bit unlock key)
4. Release PA2/RESET. The PA0/DBG pin is now identical in function to that of the
DBG pin on the 20- or 28-pin device. To enter DEBUG mode, re-autobaud and write
to the OCD control register (see
80H
Breakpoints
Execution breakpoints are generated using the
eZ8 CPU decodes a
OCD enters DEBUG mode and idles the eZ8 CPU. If breakpoints are not enabled, the
OCD ignores the BRK signal and the

byte in Flash memory. To implement a breakpoint, write
address, overwriting the current instruction. To remove a breakpoint, the corresponding
page of Flash memory must be erased and reprogrammed with the original data.
Runtime Counter
The OCD contains a 16-bit Runtime Counter. It counts system clock cycles between
breakpoints. The counter starts counting when the OCD leaves DEBUG mode and stops
counting when it enters DEBUG mode again or when it reaches the maximum count of
