Notes: • If the same bank area is set in two or more Virtual Flash L Bank Registers and accessed

while each register’s flash emulation enable bit is enabled, the data will be destroyed.

Therefore, do not set the same bank area in two or more registers.

• If any 8-Kbyte area (L bank) specified by the Virtual Flash L Bank Registers 0 to 7 is accessed,

its corresponding internal RAM area is accessed. During virtual flash emulation mode, internal RAM can be accessed

for read and write from both the internal RAM area and the virtual flash set area.

(Note 1)

Note 1: Set the eight start address bits A11-A18 of each L bank of internal flash memory that is divided in 8-Kbyte units

in the Virtual Flash L Bank Register's L bank address (LBANKAD) bits.

Note: • Because the internal flash memory of the M32185F4 is 512 Kbytes, the address b7 (A11) and b8 (A12)

must always be set to "0."
