manufacturer:linear description:programmed/erased whether the output data, dq0/dq1 at the address 7fff2, is "0" or "1". the #tbl will lock the whole 64kbytes top boot block, it will not partially lock the 16kbytes boot block. you can check the dq2/dq3 at the address 7fff2 to see whether the #tbl/#wp pin is in low or high state. if the dq2 is "0", it means the #tbl pin is tied to high state. in such condition, whether boot block can be programmed/erased or not will depend on software setting. on the other hand, if the dq2 is "1", it means the #tbl pin is tied to low state, then boot block is locked no matter how the software is set. like the dq2, the dq3 inversely mirrors the #wp state. if the dq3 is "0", it means the #wp pin is in high state, then all the sectors except the boot block can be programmed/erased. on the other hand, if the dq3 is "1", then all the sectors except the boot block are programmed/erased inhibited. |
