Read Program Memory.
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 0). If the device is not
in DEBUG mode or if the Read Protect option bit is enabled, this command returns
for the data.

Write 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 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.
returns the CRC (cyclic redundancy check) of Program Memory using the 16-bit CRC-
CCITT polynomial (x
bit of the data is shifted through the polynomial first. The CRC is inverted when it is trans-
mitted. If the device is not in DEBUG mode, this command returns
value. Unlike most other OCD Read commands, there is a delay from issuing of the com-
mand until the OCD returns the data. The OCD reads the Program Memory, calculates the
