Bit Name

Function

MODENL

0: Disable virtual flash emulation function

Virtual flash emulation L enable bit

1: Enable virtual flash emulation function

1–6

No function assigned. Fix to "0."

7–14

LBANKAD

Start address A11–A18 of the relevant L bank

L bank address bit (Note 1)

No function assigned. Fix to "0."

Note 1: Because the internal flash memory of the M32186F8 is 1M (1,024K) bytes, the address b7 (A11) must always be set to "0."

Also, because the initial flash memory of the M32185F4 is 512 Kbytes, the address b7 (A11) and b8 (A12) must always be set

to "0."

Note 2: This area exists only in the 32186 and it is use prohibitation area in the 32185.

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

(1) MODENL (Virtual Flash Emulation L Enable) bit (Bit 0)

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 be enabled for the L bank

area selected by the LBANKAD bits.

(2) LBANKAD (L Bank Address) bits (Bits 7–14)

The LBANKAD bits are provided for selecting one of the L banks that are separated every 8 Kbytes. Use

these LBANKAD bits to set the eight bits A11–A18 of the 32-bit start address of the desired L bank.

Note: • For details, see Section 6.7, “Virtual Flash Emulation Function.”
