Manufacturer:GPG 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. |
