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 can be read 1-65536 bytes at a time (65536 bytes can be read by
setting size to zero). If the device is not in DEBUG mode or if the Read Protect Option
Bit is enabled, this command returns
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 can be
written 1-65536 bytes at a time (65536 bytes can be written by setting size to zero). If
the device is not in DEBUG mode or if the 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 can be
read 1-65536 bytes at a time (65536 bytes can be read by setting size to zero). 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 CRC (cyclic redundancy check) of Program Memory using
the 16-bit CRC-CCITT polynomial. If the device is not in DEBUG mode, this
command returns
commands, there is a 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 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.
