TMP90CH45
3. Operation
This section explains the functions and basic operations of the
TMP90CH45 in blocks.
3.1 CPU
The TMP90CH845 has a built-in, high performance 8-bit CPU.
For the operation of the CPU, see the book TLCS 90
Series CPU Core Architecture.
This section explains the CPU functions unique to the The
TM90CH45 that are not explained in that book.
3.2 Memory Map
The TMP90CH45 can provide a maximum 4M byte program
and maximum 8M byte data memory.
The program memory may be allocated to the addresses
000000H ~ 3FFFFFH, while the data memory may be allo-
cated to any address 000000H ~ 7FFFFFH.
(1)
Built-in RAM
The TMP90CH45 contains a 512-byte RAM which is allo-
cated to the addresses FDC0H ~ 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 ~ FF68H this RAM area can be
used as the parameter area for micro DMA processing.
(This area can freely be used when the micro DMA
function is not used.)
(2)
Built-in I/O
The TMP90CH45 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.
