TMP90CH02/H03
3. Operation
The following explains the TMP90CH02 functions and basic
operations. The CPU functions and internal I/O functions of the
TMP90CH02 are the same as the TMP90C840A.
Refer to the “TMP90C840A” section concerning functions
which are not explained the following.
3.1 CPU
The TMP90CH02 has an internal high-performance 8-bit CPU.
Refer to the book TLCS Series CPU Core Architecture
concerning CPU operation.
3.2 Memory Map
The TMP90CH02 supports a program memory of up to 64K
bytes.
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 0000H to FFFFH.
(1)
Internal ROM
The TMP90CH02 internally contains a 16K byte ROM.
The address space from 0000H to 3FFFH is provided
to the ROM. The CPU starts executing a program from
0000H by resetting.
The addresses from 0010H to 007FH in this internal
ROM area are used for the entry area for the interrupt
processing.
The TMP90CH03 does not have a built-in ROM; there-
fore, the address space 0000H ~ 3 FFFH is used as
external memory space.
(2)
Internal RAM
The TMP90CH02 also contains a 512-byte RAM,
which is allocated to the address space FDC0H ~
FFBFH. The CPU allows the access to whole RAM
area (FF00H ~ FFBFH, 192 bytes) by a short operation
code (opcode) in the “direct addressing mode”.
The addresses from FF30H ~ FF7FH in this RAM area
can be used as parameter area for micro DMA pro-
cessing (and for any other purposes when the micro
DMA function is not used).
(3)
Internal I/O
The TMP90CH02 provides a 48-byte address space
as an internal I/O area, whose addressess 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 3.2 is a memory map indicating the areas acces-
sible by the CPU in the respective addressing mode.
