SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
BASIC FUNCTION BLOCKS
The M37702M2AXXXFP contains the following devices on a
single chip: ROM and RAM for storing instructions and data, CPU
for processing, bus interface unit (which controls instruction
prefetch and data read/write between CPU and memory), timers,
UART, A-D converter, and other peripheral devices such as I/O
ports. Each of these devices are described below.
MEMORY
The memory map is shown in Figure 1. The address space is 16
M bytes from addresses 016 to FFFFFF16. The address space is
divided into 64 K bytes units called banks. The banks are num-
bered from 016 to FF16.
Built-in ROM, RAM and control registers for built-in peripheral de-
vices are assigned to bank 016.
The 16 K bytes area from addresses C00016 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 512 bytes area from addresses 8016 to 27F16 contains the
built-in 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, UART, timer, and interrupt control regis-
ters.
A 256 bytes 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.
