DBG ← Size[7:0]
DBG → 1-256 data bytes
Write Program Memory (0AH). The Write Program Memory command writes data to
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 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 Read Protect option bit is enabled, the data is discarded.

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

Write Data Memory (0CH). The Write Data Memory command writes data to Data Mem-
ory. This command is equivalent to the LDE and LDEI instructions. Data is 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 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 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 FFH for the data.
