Operation (1) The following explains the TMP90C441 functions and basic operations. The CPU functions and internal I/O functions of the TMP90C441 are the same as the TMP90C840A. Refer to the “TMP90C840A” section concerning functions which are not explained the following. The TMP90C441 internally contains a 4K 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). 3.1 CPU The TMP90C441 has an internal high-performance 8-bit CPU. Refer to the “TLCS-90 CPU” section concerning CPU operation. 3.2 Memory Map The TMP90C441 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. 6/12 Internal RAM (2) Internal I/O The TMP90C441 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.
