Chapter 15 Locking
15.1 Locking Overview
Locking of erase blocks against writing or erasing is a feature supported by some of the M16C family
devices.
FDT offers control over these locking settings at connection, disconnection and during normal operations.
The options are available from a toolbar button and a menu entry:
Figure 15-1 ToolbarButton
Figure 15-2 Menu Entry
Each erase block that supports the feature can be locked and unlocked individually (Note: an unlock
can only be performed by erasing the block). However, the setting will have no effect until
disconnecting to the device. The lock status of each erase block can be set automatically at disconnect
by FDT.
