Memory Map
The mapping of virtual addresses to physical addresses is shown below.
Note 1: The on-chip RAM is mapped to the addresses from 0xFFFF_9800 through 0xFFFF_BFFF.
Note 2: The TMP1941AF has access to only 16 Mbytes of external physical address space. The 16-Mbyte physical

Virtual Address
memory can be located anywhere within the CPU’s 3.5-Gbyte physical address space through use of
programmable chip select signals. However, any address references to the on-chip memory, on-chip
peripheral or reserved regions override external memory access.
