Upper Layer Interface

The SafeFTL is designed for ease of use by standard file systems. It provides a very simple logical sector-based interface for the higher level application. The interface functions are:

hl_init	Initialises the SafeFTL
hl_format	Performs an initial low-level format of the flash
hl_getmaxsector	Returns the number of logical sectors in the system
hl_open	Opens one or more sectors for a read/write operation
hl_close	Closes an operation
hl_read	Reads a number of logical sectors from the flash
hl_write	Writes a number of logical sectors to the flash

This interface is suitable for use in conjunction with HCC’s FAT, THIN and EUSB-MS. Integrated projects can be provided on request.
