ISPFF
ISP Fail Flag (Write-Protection Bit)
This bit is set by hardware when a triggered ISP meets any of the following conditions:
(1) APROM writes to itself
(2) LDROM writes to itself
(3) CONFIG is erased/programmed if CFGUEN is set to 0
(4) Destination address is illegal, such as over an available range
