to configure the MMU register. For such cases, please refer to the section on the Memory
controller.
range assigned to the LOCAL area is predefined and cannot be changed.
program execution cannot be branched between different banks of the same LOCAL area using
the JP instruction. For more details, refer to the following programming examples.

Note: This device is a subset microcontroller of 900H1 series microcontroller: TMP92CZ26AXBG and
The MMU allows for memory expansion by providing three local memory areas, the MMU
For recommended address memory maps, refer to Figure 3.10.1.
However, when the amount of memory being used is less than 16 Mbytes, it is not necessary
A memory area which can be configured into banks is called the LOCAL area. The address
And the rest of the memory area is called the COMMON area.
Basically, a series of program routines should be stored entirely within one bank. The
The TMP92CF29A has the following external pins for connecting external memory.
Figure 3.10.1 shows one of recommended address memory maps. This is an example of when

TMP92CF26A. The total memory size of this device was cut from 3.1GByte to 2.1G byte because number of
pins was cut, and BANK of Z-area was cut from 512 banks to 256 banks.
