Read OCD Revision (00H)—The Read OCD Revision command determines the ver-
sion 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.
DBG
DBG
Read Runtime Counter (03H)—The Runtime Counter counts system clock cycles in
between Breakpoints. The 16-bit Runtime Counter counts up from
maximum count of
ry, 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 0 and the only method of returning the device to 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.
