Read Data Memory (0DH).
This command is equivalent to the LDE and LDEI instructions. Data can be read 1 to
65536 bytes at a time (65536 bytes can be read by setting size to 0). If the device is not in
DEBUG Mode, this command returns

bit CRC-CCITT polynomial. If the device is not in DEBUG Mode, this command returns

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 function of the
Program Memory size and is approximately equal to the system clock period multiplied by
the number of bytes in the Program Memory.

Stuff Instruction (11H).
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 Flash Read Protect Option bit is enabled, the
OCD ignores this command.

Execute Instruction (12H).

The number of bytes to send for the instruction depends on the opcode. If the device is not
