Start address A12–A19 of the relevant S bank

S bank address

Note: • These registers must always be accessed in halfwords.

(1) MODENS (Virtual Flash Emulation Enable) bit (Bit 0)

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 be enabled for the S bank

area selected by the SBANKAD bits.

(2) SBANKAD (S Bank Address) bits (Bits 8–15)

The SBANKAD bits are provided for selecting one of the S banks that are separated every 4 KB. Use these

SBANKAD bits to set the eight bits A12–A19 of the 32-bit start address of the desired S bank.

Note: • For details, see Section 6.6, “Virtual Flash Emulation Function.”
