0: Read operations are locked (disabled) for corresponding block across the JTAG interface.
1: Read operations are unlocked (enabled) for corresponding block across the JTAG inter-
face.
0: Write/Erase operations are locked (disabled) for corresponding block across the JTAG
interface.
1: Write/Erase operations are unlocked (enabled) for corresponding block across the JTAG
interface.
NOTE: When the highest block is locked, the security bytes may be written but not erased.
The content of this register is used as the high byte of the 16-bit Software Read Limit
address. This 16-bit read limit address value is calculated as 0xNN00 where NN is replaced
by content of this register on reset. Software running at or above this address is prohibited
from using the MOVX and MOVC instructions to read, write, or erase Flash locations below
this address. Any attempts to read locations below this limit will return the value 0x00.
