BASIC FUNCTION BLOCKS
These microcomputers have the same functions as the
M37920F8CGP.
Therefore, refer to the datasheet of the M37920F8CGP.
MEMORY
Figures 1 to 3 show the memory maps. The address space is 16
Mbytes from addresses 016 to FFFFFF16. The address space is di-
vided into 64-Kbyte units called banks. The banks are numbered
from 016 to FF16. Bank FF16 is a reserved area for the development
support tool. Therefore, do not use bank FF16.
Internal flash memory and internal RAM are assigned as shown in
Figures 1 to 3.
Addresses FFC016 to FFFF16 contain the RESET and the interrupt
vector addresses, and the interrupt vectors are stored there.
For details, refer to the section on interrupts.
Assigned to addresses 016 to FF16 are peripheral devices such as
I/O ports, A-D converter, UART, timers, interrupt control registers,
DMA controoler, DRAM controller, etc.
For the flash memory in the boot ROM area, refer to the section on
the flash memory mode.
