can be written 1–256 bytes at a time (256 bytes can be written by setting size to 0). If the
device is not in DEBUG Mode, the address and data values are discarded. If the Flash read
protect option bit is enabled, only writes to the Flash control registers are allowed and all
other register write data values are discarded.

can be read 1–256 bytes at a time (256 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 command
returns
Write Program Memory (0AH).
program memory. This command is equivalent to the LDC and LDCI instructions.
Data can be written 1–65536 bytes at a time (65536 bytes can be written by setting size to
0). The on-chip Flash Controller must be written to and unlocked for the programming
operation to occur. If the Flash Controller is not unlocked, the data is discarded. If the
device is not in DEBUG Mode or if the Flash read protect option bit is enabled, the data is
discarded.
