• Virtual-flash emulation function

The 32170 and 32174 have a function for mapping 8-Kbyte blocks (up to four blocks for the

M32170F6 or up to three blocks for the M32170F4, M32170F3, M32174F4, and M32174F3) of the

internal RAM beginning with its start address into the internal flash memory areas divided in units of

8 Kbytes (L banks), as well as mapping 4-Kbyte blocks (up to two blocks) of the internal RAM

beginning with address H’0080 C000 for the M32170F6 or H’0080 A000 for the M32170F4,

M32170F3, M32174F4, and M32174F3 into the internal flash memory areas divided in units of 4

Kbytes (S banks). This is referred to as the virtual-flash emulation function. For details about this

function, refer to Section 6.7, “Virtual-flash Emulation Function.”
