Read Program Memory (0BH)—The read program memory command, reads data from
program memory. This command is equivalent to the LDC and LDCI instructions. Data is
read 1–65536 bytes at a time (65536 bytes are read by setting size to 0). If the device is not
in DEBUG mode or if the Flash read protect option bit is enabled, this command returns
FFH

Write Data Memory (0CH)—The write data memory command, writes data to data
memory. This command is equivalent to the LDE and LDEI instructions. Data is written
1–65536 bytes at a time (65536 bytes are written by setting size to 0). If the device is not
in DEBUG mode or if the Flash read protect option bit is enabled, the data is discarded.

Read Data Memory (0DH)—The read data memory command, reads from data
memory. This command is equivalent to the LDE and LDEI instructions. Data is read from
1 to 65536 bytes at a time (65536 bytes are read by setting size to 0). If the device is not in
DEBUG mode, this command returns

Read Program Memory CRC (0EH)—The read program memory CRC command,
computes and returns the cyclic redundancy check (CRC) of program memory using the
16-bit CRC-CCITT polynomial. If the device is not in DEBUG mode, this command
returns
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 function of the
for the data.
