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.

Read Runtime Counter (03H)—The runtime counter counts system clock cycles in
between breakpoints. The 16-bit runtime counter counts from
maximum count of
read memory, write register, read register, read memory CRC, step instruction, stuff
instruction, and execute instruction commands.

Write OCD Control Register (04H)—The write OCD control register command writes
the data that follows to the OCDCTL register. When the Flash read protect option bit is
enabled, the DBGMODE bit (
To return the device to normal operating mode, the device must be reset.
