BASIC FUNCTION BLOCKS
The M37733M4BXXXFP has the same functions as the
M37733MHBXXXFP except for the memory allocation and the ROM
area modification function.
Refer to the section on the M37733MHBXXXFP.
MEMORY
The memory map is shown in Figure 1. The address space has a
capacity of 16 Mbytes and is allocated to addresses from 0
16
to
FFFFFF
16
. The address space is divided by 64-Kbyte unit called bank.
The banks are numbered from 0
16
to FF
16
.
Built-in ROM, RAM and control registers for internal peripheral devices
are assigned to bank 0
16
.
The 32-Kbyte area from addresses 8000
16
to FFFF
16
is the built-in
ROM. Addresses FFD6
16
to FFFF
16
are the RESET and interrupt
vector addresses and contain the interrupt vectors. Refer to the section
on interrupts for details.
The 2048-byte area allocated to addresses from 80
16
to 87F
16
is the
built-in RAM. In addition to storing data, the RAM is used as stack
during a subroutine call or interrupts.
Peripheral devices such as I/O ports, A-D converter, serial I/O, timer,
and interrupt control registers are allocated to addresses from 0
16
to
7F
16
.
Additionally, the internal ROM area can be modified by software. Refer
to the section on ROM area modification function for details.
A 256-byte direct page area can be allocated anywhere in bank 0
16
by using the direct page register (DPR). In the direct page addressing
mode, the memory in the direct page area can be accessed with two
words. Hence program steps can be reduced.
