• Virtual-flash emulation function

The 32172 has a function for mapping up to two 8-Kbyte blocks of the internal RAM beginning with

the first address into the internal flash memory areas divided in units of 8 Kbytes (L banks).

Similarly, the 32173 has a function for mapping up to three 8-Kbyte blocks of the internal RAM

beginning with the first address into the internal flash memory areas divided in units of 8 Kbytes (L

banks), as well as mapping up to two 4-Kbyte blocks of the internal RAM beginning with the H'0080

A000 area into the internal flash memory areas divided in units of 4 Kbytes (S banks) (the latter

available for only the 32173). This is referred to as the virtual-flash emulation function. For details

about this function, refer to Section 6.7, "Virtual-flash Emulation Function."
