The SRAM memory is mapped both in the program space (from 8270h to 87FFh) and in the data
space (from A70h to FFFh). The data memory can be used for real-time data acquisition and to
temporarily save variables during a TML program execution. The program space can be used to
download and execute TML programs. It is the user's choice to decide how to split the 1.5-K
SRAM into data and program memory.

The E
ROM is seen as 8K×16 program memory mapped in the address range 4000h to 5FBEh. It
offers the possibility to keep TML programs in a Non-volatile memory. Read and write accesses to
