Option Bit is enabled, this command returns FFH for all the data values.

• 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 zero). 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 Z8F640x family 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 zero). If the Z8F640x family 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
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 zero). If
the Z8F640x family device is not in Debug mode or if the Read Protect Option Bit is
enabled, the data is discarded.
