SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
BASIC FUNCTION BLOCKS
The M37754M8C-XXXGP contains the following devices on a single
chip: ROM, RAM, CPU, bus interface unit, timers, UART, A-D con-
verter, D-A converter, I/O ports, clock generating circuit and others.
Each of these devices is described below.
MEMORY
The memory map is shown in Figure 1. 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.
Internal ROM, internal RAM, and control registers for internal periph-
eral devices are assigned to bank 016.
The 60-Kbyte area from addresses 100016 to FFFF16 is the internal
ROM.
Addresses FFD216 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 from addresses 8016 to 87F16 contains the inter-
nal RAM. In addition to storing data, the RAM is used as stack during
a subroutine call, or interrupts.
Assigned to addresses 016 to 7F16 are peripheral devices such as
I/O ports, A-D converter, D-A converter, UART, timer, and interrupt
control registers.
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
using the direct page register DPR. In direct page addressing mode,
the memory in the direct page area can be accessed with two words
thus reducing program steps.
Note: Internal ROM area can be modified. (Refer to the section on ROM area modification function.)
