Notes 1. Internal ROM area can be modified. (Refer to the section on ROM area modification function.)
2. Banks 1016 – FF16 cannot be accessed in the 7735 group.
BASIC FUNCTION BLOCKS
The M37735M4BXXXFP has the same fuanctions as the
M37735MHBXXXFP except for the memory allocation and the ROM
area modification function.
Refer to the section on the M37735MHBXXXFP.
MEMORY
The memory map is shown in Figure 1. The address space has a
capacity of 16 Mbytes and is allocated to addresses from 016 to
FFFFFF16. The address space is divided by 64-Kbyte unit called bank.
The banks are numbered from 016 to FF16.
However, banks 1016 – FF16 of the 7735 group cannot be accessed.
Built-in ROM, RAM and control registers for internal peripheral devices
are assigned to bank 016.
The 32-Kbyte area from addresses 800016 to FFFF16 is the built-in
ROM. Addresses FFD616 to FFFF16 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 8016 to 87F16 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 016 to
7F16.
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 016
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.
