Program area and data area expansion using the MMU
function
The TMP90C051 offers program area and data area
expansion, depending on the MMU.
MMU not used : Program area
0 - 64KB
0 - 64KB
: Data area
:
When BX and
BY/HDMA are used 0 - 8MB

3.4.2 MMU Functions
The following register expand the 64KB logical memory
capacity (address 0000H - FFFFH) to a maximum of 8MB
(addresses 000000H - 7FFFFFH).
(1) CLLAR: Common Local Logical Address Register
(14-bit)
(2) EXPA0: Local 0 Expand Register (11-bit)
(3) EXPA1: Local 1 Expand Register (11-bit)
CLLAR is used to specify the logical addresses
0000H-FFFFH in the common 0, local 0, local 1and common
1 areas, as shown in Figure 3.4 (1).
EXPA0 is a bank register used to map the local 0 area logical
addresses specified with CLLAR to the physical address
space.
When the program area or data is indicated as being inside
the local 0 area, the EXPA0 value is added to either the current
program address value or memory address value to generate the
physical addresses.
EXPA1 functions in the same way as EXPA0.
