(2) Boot ROM memory map
(3) Reset/interrupt address conversion circuit
This section describes the built-in boot ROM.
For the specification of S/W in boot ROM, refer to 3.20 boot ROM sections.
Note: As the last 16-byte area (FFFFF0H to FFFFFFH) is reserved for an emulator, this

((B) area). Following boot sequence, the area can be changed to (A) area by setting
BROMCR<VACE> to “0”. Therefore, (A) area can be used only for the application
system program.
register has no effect.
BOOT mode is started by following AM1 and AM0 pins condition with reset.
Boot ROM consists of an 8-Kbyte masked ROM and is assigned to address 3FE000H
The Reset/interrupt vector area is assigned to FFFF00H to FFFFEFH ((A) area) in
Since the boot ROM is assigned to another area, a reset/interrupt vector address
In BOOT mode, the reset/interrupt vector area is assigned to 3FFF00H to 3FFFEFH
This <VACE> is initialized to “1” in BOOT mode. In any other starting mode, this
area is not changed by the <VACE> register.
