Note: This register must always be accessed in halfword.
(1) MODENS (Virtual Flash Emulation Enable) bit (D0)
The MODENS 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 S bank area selected by the SBANKAD bits.
(2) SBANKAD (S Bank Address) bits (D8-D15)
The SBANKAD bits are provided for selecting one S bank from a total of 192 S banks separated
every 4 KB. Use these SBANKAD bits to set the eight bits, A12-A19, of the 32-bit start address of
the S bank you want to select.
(For details, refer to Section 6.7, "Virtual Flash Emulation Function.")
