Step Instruction (10H)—The Step Instruction command steps one assembly
instruction at the current Program Counter (PC) location. If the device is not in
DEBUG mode or the Read Protect Option Bit is enabled, the OCD ignores this
command.
Stuff Instruction (11H)—The Stuff Instruction command steps one assembly
instruction and 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 Breakpoint. If the device is not in DEBUG mode or the Read Protect
Option Bit is enabled, the OCD ignores this command.
Execute Instruction (12H)—The Execute Instruction command allows sending an
entire instruction to be executed to the eZ8 CPU. This command can also step over
Breakpoints. The number of bytes to send for the instruction depends on the opcode. If
the device is not in DEBUG mode or the Read Protect Option Bit is enabled, the OCD
ignores this command
DBG ← 10H
DBG ← 11H
DBG ← opcode[7:0]
DBG ← 12H
DBG ← 1-5 byte opcode
