Read OCD Revision (00H)—The Read OCD Revision command determines the
version of the On-Chip Debugger. If OCD commands are added, removed, or
changed, this revision number changes.
Read OCD Status Register (02H)—The Read OCD Status Register command reads
the OCDSTAT register.
Write OCD Control Register (04H)—The Write OCD Control Register command
writes the data that follows to the OCDCTL register. When the Read Protect Option
Bit is enabled, the DBGMODE bit (OCDCTL[7]) can only be set to 1, it cannot be
cleared to 0 and the only method of putting the device back into normal operating
mode is to reset the device.
Read OCD Control Register (05H)—The Read OCD Control Register command
reads the value of the OCDCTL register.
Write Program Counter (06H)—The Write Program Counter command writes the
data that follows to the eZ8 CPU’s Program Counter (PC). If the device is not in
