#161341 - what is pgr7? Responding to: ???'s previous message |
Is it bit 7 of the page register? (I don't have time to look into the datasheet right now).
You should really start using the terminology ST uses in the datasheet. The main FLASH is split to 8 *sectors*, and each sector has a chip select output from the DPLD, called fs0 through fs7. Even if you omit the pgr7 from the equations, the "(page==5)" in the fs5 equation says, that you will need to put 5 into the page register to be able to use sector 5 on addresses 8000-FFFF; similarly for sector 6. Unless I am not mistaken, of course, which might quite easily be the case (as I said, it's been a long time, and I don't have these things at hand anymore)... JW |

| you already do have page register bits involved... | 01/01/70 00:00 | |
