Bit 9 – PFSLOCK Note: This field can only be modified when BUSY=0, PFSLOCK=0, and KEY=<SWAPKEY Value>
Writing a 0 to this bit has no effect.
Writing a 1 to this bit will set the lock bit.
Note:
- Once set, PFSLOCK can only be cleared by a reset.
- This field can only be modified when STATUS.BUSY=0, PFSLOCK=0, and KEY.KEY=<SWAPKEY Value>.
| Value | Name | Description |
|---|---|---|
| 1 | LOCKED | PFSLOCK and PFSWAP cannot be written |
| 0 | UNLOCKED | PFSLOCK and PFSWAP can be written |
