TMP90C800/801
3. Operation
This chapter describes the functions and the basic operations
of the TMP90C400/401 in every block.
The function of TMP90C800 is exactly same as that of
TMP90C400 except the internal ROM/RAM size. Refer to the
TMP90C400 except the function which are not described this
section.
3.1 CPU
The TMP90C800 includes a high performance 8-bit CPU. For
the function of the CPU, see the book TLCS Series CPU
Core Architecture concerning CPU operation.
3.2 Memory Map
The TMP90C800 supports a program memory of up to 56K
bytes.
The program and data memory may be assigned to the
address space from 0000H to FFFFH.
(1)
Internal ROM
The TMP90C800 internally contains an 8K-byte ROM.
The address space from 0000H to 1FFFH is provided
to the ROM. The CPU starts executing a program from
0000H by resetting.
The addresses 0010H to 005FH in this internal ROM area
are used for the entry area for the interrupt processing.
The TMP90C801 does not have a built-in ROM; therefore,
the address space 0000H to 1FFFH is used as exter-
nal memory space.
(2)
Internal RAM
The TMP90C800 also contains a 256-byte RAM,
which is allocated to the address space from FF80H to
FF7FH. The CPU allows the access to a certain RAM
area (FF00H to FF7FH, 256 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 TMP90C800 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 3.1 is a memory map indicating the areas
accessible by the CPU in the respective addressing
mode.
