Read Register (09H). The Read Register command reads data from the Register File.
Data can be read 1â256 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 com-
mand 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 1â65536 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 opera-
tion 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.

Program Memory. This command is equivalent to the LDC and LDCI instructions. Data
can be read 1â65536 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 com-
mand 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 can be written
1â65536 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.
