→ 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 to and unlocked for the programming oper-

ation 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 dis-

carded.

• 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 Flash 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

Memory. This command is equivalent to the LDE and LDEI instructions. Data can be writ-

ten 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 dis-

carded.

• Read Data Memory (0DH)—The Read Data Memory command reads from Data Mem-

ory. 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.
