(1) MODENL (Virtual Flash Emulation Enable) bit (D0)
The MODENL bit can be set to 1 after entering virtual flash emulation mode (by setting the
FEMMOD bit to 1 while the FENTRY bit = 0). This causes the virtual flash emulation function to
become effective for the L bank area selected by the LBANKAD bits.
(2) LBANKAD (L Bank Address) bits (D8-D14)
The LBANKAD bits are provided for selecting one L bank from a total of 96 L banks separated
every 8 KB. Use these LBANKAD bits to set the seven bits, A12-A18, of the 32-bit start address
of the L bank you want to select.
(For details, refer to Section 6.7, "Virtual Flash Emulation Function.")
Note: The M32170F4 and M32170F3 do not have Virtual Flash L Bank Register 3 (FELBANK3).
