the 16-bit CRC-CCITT polynomial (x
The least-significant bit of the data is shifted through the polynomial first. The CRC is
inverted when it is transmitted. If the device is not in DEBUG mode, this command re-
turns
delay from issuing of the command until the OCD returns the data. The OCD reads the
Program Memory, calculates the CRC value, and returns the result. The delay is a func-
tion of the Program Memory size and is approximately equal to the system clock period
multiplied by the number of bytes in the Program Memory.

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.
Write Line Control Register (18H)—The Write Line Control Register command
writes the data that follows to the Line Control register.
Read Line Control Register (19H)—The Read Line Control Register command
returns the current value in the Line Control register.
