Read Register (09H)—The Read Register command reads data from the Register
File. Data 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 en-
abled, this command returns

Write Program Memory (0AH)—The Write Program Memory command writes
data to Program Memory. This command is equivalent to the LDC and LDCI instruc-
tions. Data can be written 1–65536 bytes at a time (65536 bytes can be written by set-
ting 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.

Read Program Memory (0BH)—The Read Program Memory command reads data
from Program Memory. This command is equivalent to the LDC and LDCI instruc-
tions. 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

Write Data Memory (0CH)—The Write Data Memory command writes data to
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 Flash Read Protect Option bit is en-
abled, the data is discarded.
