TMP90C141
3. Operation
The following explains the TMP90C141 functions and basic
operations. The CPU functions and internal I/O functions of the
TMP90C141 are the same as the TMP90C840A.
Refer to the “TMP90C840A” section concerning functions
which are not explained the following.
3.1 CPU
The TMP90C141 has an internal high-performance 8-bit CPU.
Refer to the “TLCS-90 CPU” section concerning CPU
operation.
3.2 Memory Map
The TMP90C141 supports a program memory of up to 64K
bytes and a data memory of maximum 1M 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 00000H to FFFFFH.
(1)
Internal RAM
The TMP90C141 internally 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
operation code (opcode) in a “direct addressing
mode”.
The addresses from FF10H to FF7FH 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).
(2)
Internal I/O
The TMP90C141 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 3.1 is a memory map indicating the areas
accessible by the CPU in the respective addressing mode.
