The af f ect ed sectors are S0 and S1 in a bottom-boot device, or S37 and S38 in a top-boot device. If the pin is placed at VIH, the protection state of those tw o sectors reverts to whether they were last set to be protected or unprotected using the method described in the Sector Group Protection and Unprotection sections. Accelerate Function: If VHH is applied to this input, the device enters the Unlock Bypass mode, t empor ar ily unpr ot ect s any pr ot ect ed sect or s, and uses t he higher voltage on the pin to reduce the time required for program operations. The syst em w ould t hen use t he t w o- cycle pr ogr am command sequence as required by the Unlock Bypass mode. Removing VHH from the pin returns the device to normal operation. This pin must not be at VHH for operations other than accelerated programming, or devic e damage may r es ult . Leaving t he pin unc onnec t ed may r es ult in inconsistent device operation. |
