16.3.1. Summary of Flash Security Options
There are three Flash access methods supported on the C8051F060/1/2/3/4/5/6/7; 1) Accessing Flash
through the JTAG debug interface, 2) Accessing Flash from firmware residing below the Flash Access
Limit, and 3) Accessing Flash from firmware residing at or above the Flash Access Limit.
Accessing Flash through the JTAG debug interface:
Accessing Flash from firmware residing below the Flash Access Limit:
Accessing Flash from firmware residing at or above the Flash Access Limit:
1. The Read and Write/Erase Lock bytes (security bytes) provide security for Flash access
2. Any unlocked page may be read from, written to, or erased.
3. Locked pages cannot be read from, written to, or erased.
4. Reading the security bytes is always permitted.
5. Locking additional pages by writing to the security bytes is always permitted.
6. If the page containing the security bytes is unlocked, it can be directly erased. Doing so will
7. If the page containing the security bytes is locked, it cannot be directly erased. To unlock the
8. The Reserved Area cannot be read from, written to, or erased at any time.
1. The Read and Write/Erase Lock bytes (security bytes) do not restrict Flash access from user
