Write Data Memory—
This command is equivalent to the LDE and LDEI instructions. Data can be written 1 to
65536 bytes at a time (65536 bytes can be written by setting size to 0). If the device is not
in DEBUG mode or if the Read Protect option bit is enabled, the data is discarded.

Read Program Memory CRC—
and returns the CRC (cyclic redundancy check) of Program Memory using the 16-bit
CRC-CCITT polynomial (x
icant 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 returns
CRC value. Unlike most other OCD Read 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.
