TMP90C400/401
3.2 Memory Map
The TMP90C400 supports a program memory and a data
memory of up to 60K bytes.
The program and data memory may be assigned to the
address space from 0000H to FFFFH.
(1)
Internal ROM
The TMP90C400 internally contains an 4K-byte ROM.
The address space from 0000H ~ 0FFFH is provided
to the ROM. The CPU starts executing a program
from 0000H by resetting.
The addresses 0010H ~ 005FH in this internal ROM area
are used for the entry area for the interrupt processing.
The TMP90C401 does not have a built-in ROM; therefore,
the address space 0000H ~ 0FFFH is used as external
memory space.
(2)
Internal RAM
The TMP90C400 also contains a 128-byte RAM,
which is allocated to the address space from FF00H ~
FF7FH. The CPU allows the access to a certain RAM
area (FF00H ~ FF7FH, 128 bytes) by a short operation
code (opcode) in a “direct addressing mode”.
The addresses from FF20H to FF5FH in this RAM area
can be used as parameter area for micro DMA processing
(and for any other purposes when the micro DMA
function is not used).
(3)
Internal I/O
The TMP90C400 provides a 32-byte address space as
an internal I/O area, whose addresses range from FF80H
to FF9FH. This I/O area can be accessed by the CPU
using a short opcode in the “direct addressing mode”.
Figure 3.2 is a memory map indicating the areas
accessible by the CPU in the respective addressing mode.
