Read Program Memory (0BH).
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 0). If the
device is not in DEBUG Mode or if the Flash read protect option bit is enabled, this com-

ory. 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 flash read protect option bit is enabled, the data is discarded.
Read Data Memory (0DH).
This command is equivalent to the LDE and LDEI instructions. Data can be read from 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
Read Program Memory CRC (0EH).
putes 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
