TMP90CH44
3. Operation
The following explains the TMP90CH44 functions and basic
operations. The CPU functions and internal I/O functions of
the TMP90CH44 are the same as the TMP90C844.
Refer to the “TMP90C844” section concerning functions
which are not explained in the following.
3.1 CPU
The TMP90CH44 has an internal high performance 8-bit CPU.
Refer to the book TLCS 90 Series CPU Core Architecture
section concerning the CPU operation.
3.2 Memory Map
The TMP90CH44 can provide a maximum 48K byte program
and data memory.
The program and data memories may be allocated to the
address 0000H ~ FFFFH.
(1)
Built-in ROM
The TMP90CH44 has an internal 16K-byte ROM. This
ROM is located at addresses 0000H ~ 3FFFH. Program
execution starts from address 0000H after a reset
operation.
Addresses 0008H ~ 0078H in the internal ROM area are
used as the interrupt processing entry area.
(2)
Built-in RAM
The MP90CH44 contains a 512-byte built-in RAM which is
allocated to the addresses FFC0H ~ FFBFH. The CPU
can also access some portions of the RAM (192 byte
area FF00H ~ FFBFH) using short instruction codes in
the direct addressing mode.
Addresses of FF18H ~ FF78H this RAM area can be
used as the parameter area for micro DMA process-
ing. (This area can freely be used when the micro DMA
function is not used.)
(3)
Built-in I/O
The TMP90CH44 uses 56 bytes of the address space as
a built-in I/O area. The area is allocated to the addresses
FFC0H ~ FFF7H. The CPU can access the built-in I/O
using short instruction codes in the direct addressing
mode.
Figure 3.2 shows the memory map and the access
ranges of the CPU for each addressing mode.
