Caution:
Flash Read Protection
Flash Write/Erase Protection
Flash programming and erasure are not supported for system clock frequencies below
32 kHz, above 20 MHz, or outside of the device’s operating frequency range. The Flash
Frequency High and Low Byte registers must be loaded with the correct value to ensure
proper Flash programming and erase operations.
The user code within Flash memory can be protected from external access. Programming
the Flash Read Protect option bit prevents the reading of user code by the OCD or by using
the Flash Controller Bypass mode. For more information, see
On-Chip Debugger on page
The Z8FMC16100 Series Flash MCU device provides several levels of protection against
