Dear Ti,

看了doc 還是不懂flash lock怎麼使用

請問有教學嗎？

還是可以提供一下步驟。

Thanks

Lock Bits
For software and/or access protection, a set of lock bits can be written to the upper available flash
page—the lock-bit page. The lock-bit structure consists of 128 bits where the first (FLASH_PAGES-1)
each corresponds to the first flash pages available in the device. The last bit (at the highest address) is
the debug lock bit (see Table 3-5). The structure starts at address 0x7FF0 (address 0xFFF0 in XDATA)
when the upper flash bank is mapped in, and occupies 16 bytes. The rest of the lock-bit page can be used
to store code or constants, but cannot be changed without entering debug mode.
The PAGELOCK[FLASH_PAGES-2:0] lock-protect bits are used to enable erase and write protection for
individual flash memory pages (2 KB; 1 KB on CC2533). There is one bit for each available page.
When the debug-lock bit, DBGLOCK, is set to 0 (see Table 3-5), all debug commands except
CHIP_ERASE, READ_STATUS, and GET_CHIP_ID are disabled. The status of the debug-lock bit can be
read using the READ_STATUS command (see Section 3.3.2).
Note that after the debug-lock bit has changed due to a write to the lock-bit page or a CHIP_ERASE
command, the device must be reset to lock or unlock the debug interface.
Issuing a CHIP_ERASE command is the only way to clear the debug-lock bit, thereby unlocking the debug
interface.
Table 3-5 defines the 16-byte structure containing the flash lock-protection bits. Bit 0 of the first byte
contains the lock bit for page 0, bit 1 of the first byte contains the lock bit for page 1, and so on. Bit 7 of
the last byte in the flash is the DBGLOCK bit (bit 127 in the structure).

對不起，cc2541 好像找不到PAGELOCK跟DBGLOCK

請問有別的方法嗎？
