TMP90CM40
3. Operation
The following explains the TMP90CM40 function and basic
operations. The CPU functions and internal I/O functions of
the TMP90CM40 are the same as the TMP90C840A.
Refer to the “TMP90C840A” section concerning functions
which are not explained in the following.
3.1 CPU
The TMP90CM40 has an internal high-performance 8-bit
CPU.
Refer to the book TLCS 90 Series CPU Core Architec-
ture concerning CPU operation.
3.2 Memory Map
The TMP90CM40 supports a program memory of up to 64K
bytes and a data memory of maximum 1Mbytes.
The program memory may be assigned to the address
space from 00000H to 0FFFFH, while the data memory can
be allocated to any address from 00000H to FFFFFH.
(1)
Internal ROM
The TMP90CM40 internally contains a 32K byte ROM.
The address space from 0000H to 7FFFH is provided to
the ROM. The CPU starts executing a program from
0000H by resetting.
The addresses 0010H to 007FH in this internal ROM
area are used for the entry area for the interrupt processing.
(2)
Internal RAM
The TMP90CM40 also contains a 1K byte RAM, which
is allocated to the address space from FBC0H to
FFBFH. The CPU allows the access to a certain RAM
area (FF00H to FFBFH, 192 bytes) by a short opera-
tion code (opcode) in a “direct addressing mode”.
The addresses FF10H to FF7FH in this internal RAM
area can be used as parameter area for micro DMA
processing (and for any other purpose when the micro
DMA function is not used).
(3)
Internal I/O
The TMP90CM40 provides a 48-byte address space
as an internal I/O area, whose addresses range from
FFC0H to FFEFH. This I/O area can be accessed by
the CPU using a short opcode in the “direct
addressing mode”.
Figure 3.1 (1) is a memory map indicating the areas
accessible by the CPU in the respective addressing
mode.
