This system call is regarded as internal operating system usage but may be used by applications.
The routine will internally ask the Flash Memory for identification and intelligently use the correct erasing algorithm. All known Flash Memory chips from INTEL, AMD & AMIC (see flashepr.def) uses 64K sectors, except the AM29F010B 128K chip, which uses 16K sectors.
Important:
INTEL I28Fxxxx series Flash chips require the 12V VPP pin in slot 3 to successfully erase a block/sector on the memory chip. If the Flash Eprom card is inserted in slot 1 or 2, this routine will automatically report a sector erase failure error.
It is the responsibility of the application (before using this call) to evaluate the Flash Memory (using the OS_Fep, FEP_CDID API) and warn the user that an INTEL Flash Memory Card requires the Z88 slot 3 hardware, so this type of unnecessary error can be avoided.
