Read OCD Status Register—
OCDSTAT register.
DBG
DBG
Read OCD Counter Register—
clock cycles in between break points, generate a BRK when it counts down to 0, or
generate a BRK when its value matches the Program Counter. As this register is a down
counter, the returned value is inverted, when this register is read so the returned result
appears to be an up counter. If the device is not in DEBUG mode, this command returns
FFFFh

Write OCD Control Register—
that follows to the OCDCTL register.

DBG
Write Program Counter—
follows to the eZ8 CPU’s Program Counter (PC). If the device is not in DEBUG mode or
if the Read Protect option bit is enabled, the PC values are discarded.
