Stuff Instruction.
allows specification of the first byte of the instruction. The remaining 0–4 bytes of the
instruction are read from Program Memory. This command is useful for stepping over
instructions where the first byte of the instruction has been overwritten by a break point. If
the device is not in DEBUG mode or the Read Protect option bit is enabled, the OCD
ignores this command.

number of bytes to send for the instruction depends on the Op Code. If the device is not in

The OCD Control Register, shown in Table 135, controls the state of the On-Chip Debug-
ger. This register enters or exits DEBUG mode and enables the BRK instruction. It can
also reset the Z8FMC16100 Series Flash MCU.
